On global location-domination in graphs
A dominating set of a graph is called locating-dominating, LD-set for
short, if every vertex not in is uniquely determined by the set of
neighbors of belonging to . Locating-dominating sets of minimum
cardinality are called -codes and the cardinality of an LD-code is the
location-domination number . An LD-set of a graph is global
if it is an LD-set of both and its complement . The global
location-domination number is the minimum cardinality of a
global LD-set of . In this work, we give some relations between
locating-dominating sets and the location-domination number in a graph and its
complement.Comment: 15 pages: 2 tables; 8 figures; 20 reference

Sobre un seudónimo de fray Hortensio Félix Paravicino
En 1623, Juan Ruiz de Alarcón preparó por encargo el Elogio descriptivo, una relación de las fiestas de toros y cañas celebradas para honrar al príncipe de Gales. Esta serie de setenta y tres octavas inspiró las décimas satíricas de varios poetas, entre ellos Góngora, Quevedo y Lope de Vega. Una de las espinelas está firmada por fray Juan Centeno, del que no hay información en los repertorios bibliográficos. Tal nombre se corresponde con el seudónimo que empleó fray Hortensio Félix Paravicino en un certamen poético organizado en Toledo en 1616. Este artículo analiza la tendencia del trinitario a ocultarse bajo seudónimos y su renuencia a publicar sus poemas, así como las décimas contra Alarcón y su difusión, y propone que Paravicino es el autor del poema satírico atribuido a fray Juan Centeno.In 1623, Juan Ruiz de Alarcón prepared the Elogio descriptivo, a commissioned narration of the bullfight and cañas celebration in honour of the Prince of Wales. This series of seventy-three octavas inspired the satirical decimas by several poets, as Góngora, Quevedo and Lope de Vega. One of them is signed by fray Juan Centeno, of which there is no information in bibliographical catalogues. This name corresponds to the pseudonym used by fray Hortensio Félix Paravicino in a literary competition organised in Toledo in 1616. This article analyses the tendency of the trinitarian friar to hide himself behind pseudonyms and his reluctance to publish his poems, as well as the décimas against Alarcón and their transmission, and suggests that Paravicino is the author of the satirical poem attributed to fray Juan Centeno
