ArtMaps: A Technology for Looking at Tate’s Collection
This article presents ArtMaps, a crowdsourcing web-based app for desktop and mobile use that allows users to locate, move and annotate artworks in the Tate collection in relation to one or more sets of locations. Here the authors show that ArtMaps extends the ‘space’ of the museum and facilitates a new, pluriperspectival, way of looking at art
Community Reclamation: the Hybrid Building
Reclamation of a city involves reusing abandoned buildings in conjunction with new construction. These negative spaces of disuse generated by a changing infrastructure are often overlooked or destroyed. If they are instead viewed as positive spaces for reuse, a city’s infrastructure and its residents can adapt and grow.
Recognizing these newly positive spaces produces a chance to examine what social needs of the community are not being met. Pushing the modern concept of the hybrid building creates a unique opportunity; flexibility of use derived from flexibility of space. A community building can best serve the social needs of its residents by having the ability to adapt to changes in those needs
Complex multiplication and Brauer groups of K3 surfaces
Inspired by the classical theory of CM abelian varieties, in this paper we
discuss the theory of complex multiplication for K3 surfaces. Let be a
complex K3 surface with complex multiplication by the maximal order
of a CM field . We compute the field of moduli of triples
, where denotes the transcendental lattice of , a finite, -invariant subgroup and an
isomorphism. If is defined over a number field , we show how our results
can be efficiently implemented to study the Galois-invariant part of the
geometric Brauer group of . As an application, we list all the possible
groups that can appear as when has (geometric)
maximal Picard rank, is the field of moduli of
and denotes its absolute Galois group
Creativity and Art Education: Gaps Between Theories and Practices
Theories of creativity from different disciplines map onto teaching strategies within the fine art field. In particular, the outcomes of historical studies by psychologists and experimental studies within cognitive science have significant resonance with some long-standing methods of teaching artists. Through a series of interviews with experienced teachers of studio art in the UK university context, and analysis of written material to support teaching, this paper recognizes the need for a more systematic exploration of how creative thinking may have been embedded in the teaching of artists. We identify the presence of practical strategies, field knowledge, artistic identity, and the importance of ‘space’ within the accounts of teaching and the documents considered. We note that notions of identity and space are not clearly present within existing models of creativity, but aspects of them reflect tolerance for ambiguity. We conclude by reflecting that this space within conceptions of fine art education is a gap that needs attention and that the field that generates the creative practitioners of the future should understand creativity
Bounding Selmer groups for the Rankin--Selberg convolution of Coleman families
Let and be two cuspidal modular forms and let be a
Coleman family passing through , defined over an open affinoid subdomain
of weight space . Using ideas of Pottharst, under certain
hypotheses on and we construct a coherent sheaf over which interpolates the Bloch-Kato Selmer group of the
Rankin-Selberg convolution of two modular forms in the critical range (i.e. the
range where the -adic -function interpolates critical values of the
global -function). We show that the support of this sheaf is contained in
the vanishing locus of .Comment: Final version. To appear in Canadian Jour. Mat
