La ancestría diaguita, una filiación restituída
En la búsqueda por comprender los procesos de revisibilización indígena, este trabajo se propone abordar, en su especificidad, la reaparición pública del pueblo diaguita en la provincia de Salta, ello a partir del análisis de un caso: la comunidad Juan Calchaquí de Villa Floresta (Ciudad de Salta). Tras ese objetivo, este trabajo hace una primera aproximación a la reconstrucción etnográfica de la conformación del colectivo, en tanto se considera que ésta constituiría una estrategia analítica para comprender los modos en que operan y se desenvuelven estas dinámicas de autorreconocimento indígena.Fil: Sabio Collado, María Victoria.

On the pillars of Functional Analysis
Funding for open access charge: Universidad de Granada/CBUA. This work is supported in part by Grupo de Investigacion FQ199 of the Junta de Andalucia (Spain) and by the IMAG-Maria de Maeztu Grant CEX2020-001105-M/AEI/10.13039/501100011033..Many authors consider that the main pillars of Functional Analysis are the Hahn–Banach
Theorem, the Uniform Boundedness Principle and the Open Mapping Principle. The first
one is derived from Zorn’s Lemma, while the latter two usually are obtained from Baire’s
Category Theorem. In this paper we show that these three pillars should be either just two
or at least eight, since the Uniform Boundedness Principle, the Open Mapping Principle and
another five theorems are equivalent, as we show in a very elemental way. Since one can
give an almost trivial proof of the Uniform Boundedness Principle that does not require the
Baire’s theorem, we conclude that this is also the case for the other equivalent theorems that,
in this way, are simultaneously proved in a simple, brief and concise way that sheds light on
their nature.Universidad de Granada/CBUAJunta de Andalucia FQ199IMAG-Maria de Maeztu Grant CEX2020-001105-M/AEI/10.13039/50110001103
Analytic aspects of evolution algebras
We prove that every evolution algebra A is a normed algebra, for an l1-norm defined in terms of a fixed natural basis. We further show that a normed evolution algebra A is a Banach algebra if and only if A=A1⊕A0, where A1 is finite-dimensional and A0 is a zero-product algebra. In particular, every nondegenerate Banach evolution algebra must be finite-dimensional and the completion of a normed evolution algebra is therefore not, in general, an evolution algebra. We establish a sufficient condition for continuity of the evolution operator LB of A with respect to a natural basis B, and we show that LB need not be continuous. Moreover, if A is finite-dimensional and B={e1,…,en}, then LB is given by Le, where e=∑iei and La is the multiplication operator La(b)=ab, for b∈A. We establish necessary and sufficient conditions for convergence of (Lna(b))n, for all b∈A, in terms of the multiplicative spectrum σm(a) of a. Namely, (Lna(b))n converges, for all b∈A, if and only if σm(a)⊆Δ∪{1} and ν(1,a)≤1, where ν(1,a) denotes the index of 1 in the spectrum of La.The second author acknowledges funding from: the Distinguished Visitor Programme of the

Classifying Evolution Algebras of Dimensions Two and Three
We classified evolution algebras of dimensions two and three. Evolution algebras of
dimensions three were classified recently obtaining 116 non-isomorphic types of algebras. Herein,
with a new approach, we classify these algebras into 14 non-isomorphic types of algebra, so that this
new classification is easier to deal with.This work was partially supported by the Spanish Project MTM2016-76327-C3-2-P (AEI\FEDER, UE)
The multiplicative spectrum and the uniqueness of the complete norm topology
We define the spectrum of an element a in a non-associative algebra A according to a classical notion of invertibility (a is invertible if the multiplication operators La and Ra are bijective). Around this notion of spectrum, we develop a basic theoretical support for a non-associative spectral theory. Thus we prove some classical theorems of automatic continuity free of the requirement of associativity. In particular, we show the uniqueness of the complete norm topology of m-semisimple algebras, obtaining as a corollary of this result a well-known theorem of Barry E. Johnson (1967). The celebrated result of C.E. Rickart (1960) about the continuity of dense-range homomorphisms is also studied in the non-associative framework. Finally, because non-associative algebras are very suitable models in genetics, we provide here a hint of how to apply this approach in that context, by showing that every homomorphism from a complete normed algebra onto a particular type of evolution algebra is automatically continuous.Research supported by Junta de Andaluc´ıa grant FQM 0199
Pulse Processes in Networks and Evolution Algebras
In this paper, we merge two theories: that of pulse processes on weighted digraphs and
that of evolution algebras. We enrich both of them. In fact, we obtain new results in the theory of
pulse processes thanks to the new algebraic tool that we introduce in its framework, also extending
the theory of evolution algebras, as well as its applications.This work was partially supported by the Spanish Project MTM2016-76327-C3-2-P (AEInFEDER, UE)
Levantamiento gráfico, estudio histórico y propuesta de cambio de uso del palacio Torre Mena
El presente objeto de este trabajo, trata del levantamiento gráfico y cambio de uso del edificio
Torre Mena, emplazado en Badalona en el distrito de Llefià, concretamente en el barrio de
Sant Antoni.
Se trata de una edificación aislada con alineación a vial, de planta baja más dos pisos.
Presenta una tipología estructural de muros de carga y forjados unidireccionales. Está formado
por un volumen con una forma geométrica en planta similar a una “L”, esta coronado por una
torre cuadrada en el centro.
El proyecto lo hemos estructurado en tres fases:
Levantamiento gráfico, se realiza in situ se tomaran las medidas del edificio, tanto de las
plantas como de las fachadas con visitas frecuentes a la Torre. Así como los croquis de
las plantas. Para el levantamiento se emplearan una serie herramientas, que harán más
efectivas la toma de datos tales como un medidor laser, cinta métrica y una cámara
fotográfica.
Estudio histórico, consiste en la búsqueda de información sobre los orígenes de la Torre
y los cambios que ha sufrido a lo largo de la historia.
En el estudio histórico además de la bibliografía consultada, se ha tenido la oportunidad
de tener encuentros con técnico y personas especialistas en historia de Badalona.
Cambio de uso: El edificio no presenta patologías, ya que se encuentra en buen estado,
tras la última reforma, pero sí que tiene defectos constructivos que no cumplen con la
normativa del CTE. Una vez recopilada la y ordenada toda la información de las
anteriores fases, se propone dar un nuevo cambio de uso, con la finalidad de cambiar la
escuela actual en un centro polivalente.
Otros objetivos y no menos importantes es mantener la estética del edificio ya que se
encuentra catalogado, mantener elementos constructivos del año de construcción.
En el cambio de uso, se tendrá en cuenta la normativa actual de aplicación y se realizará
según las exigencias del Código Técnico de la Edificación. Teniendo en cuenta criterios medio
ambientales
How to incorporate urban complexity, diversity and intelligence into smart cities initiatives
Under the term “Smart City”, numerous technology-based initiatives are emerging to help cities face contemporary challenges while the concept itself is evolving towards a more holistic approach. Nevertheless, the capability of smart initiatives to provide an integrated vision of our cities is still very limited. Eventually, many of these initiatives fail to understand the complexity, diversity and intelligence that characterize contemporary cities. The purpose of this paper is to display an urban functional system, capable of interpreting the city in a more holistic way and of facilitating effective involvement of local stakeholders in the planning process of SCs initiatives
Incorporating a systemic and foresight approach into smart city initiatives: The case of Spanish cities
Descripción de un enfoque sistémico que permite analizar las iniciativas Smart Cities de forma integrada y utilizando herramientas de prospectiva.
At the dawn of the twenty-first century, cities face serious societal, economic, environmental, and governance challenges. Under the term “Smart City,” numerous technology-based initiatives are emerging to help cities face contemporary challenges while the concept itself is evolving towards a more holistic approach. Nevertheless, the capability of smart initiatives to provide an integrated vision of our cities is still very limited. Eventually, many of these initiatives do not fulfill satisfactorily their initial objectives because they fail to understand the complexity, diversity, and uncertainty that characterize contemporary cities. The purpose of this paper is twofold: to display an urban functional system, capable of interpreting the city in a more holistic way, and to incorporate foresight tools so as to formulate Smart City visions in a more participatory way with the involvement of local stakeholders
Between state management logics and indigenousdemands for classification: the recognition of thekollas and diaguitas peoples in the province of Salta(1984-2003)
Este artículo analiza el proceso de reconocimiento formal de los pueblos diaguita y kolla en la Provincia de Salta, cuyas pertenencias indígenas no fueron consideradas por los organismos indigenistas locales sino hasta principios del siglo XXI. Para ello aborda un conjunto de políticas estatales de orden censal y legislativo, en contrapunto con agencias involucradas en procesos organizativos indígenas, tanto en los Valles Calchaquíes como en los Valles Interandinos, en un lapso de dos décadas (1983-2003). Se detiene en un evento de 2003 que habilita la incorporación de representantes de ambos pueblos al Instituto Provincial de Pueblos Indígenas de Salta, marcando una inflexión tanto en las luchas colectivas como en la misma lógica de clasificación y administración de las alteridades del Estado provincial.This article analyses the formal recognition process of diaguita and kolla people in the Province of Salta, whose indigenous identities had not been considered by local institutions until the beginning of the XXI century. To achieve this, legislative and census policies were approached contrary to agencies involved in indigenous organizational processes in two decades (1983 -2003). It concluded in 2003 with an event that resulted in the representative incorporation of both groups to the indigenous institute of Salta. It was a turning point in both collective struggles and in the logical classification and administration of the otherness of the state.Fil: Sabio Collado, María Victoria.
