María Josefa Wonenburger Planells: Mujer y Matemática
(Real Sociedad Matemática Española, 2006)
[Resumen] En el artículo se describe la vida personal y profesional de la matemática María Wonenburger, mujer que desarrolló su carrera en una época en la que las mujeres tenían un acceso dificil a las carreras científicas ...
Resolving Sets Tolerant to Failures in Three-Dimensional Grids
(Springer Nature, 2022)
[Abstract] An ordered set S of vertices of a graph G is a resolving set for G if every vertex is uniquely determined by its vector of distances to the vertices in S. The metric dimension of G is the minimum cardinality of ...
El proyecto “Geometría aplicada”
(Universidade da Coruña, 2020)
[Resumen]: El proyecto “Geometría aplicada” ha sido seleccionado en la III edición de la exposición “Campus Vivo. Investigar en la Universidad”, una iniciativa de la Conferencia de Rectores de las Universidades Españolas ...
Contact detection between a small ellipsoid and another quadric
(Elsevier, 2022-08-03)
[Abstract] We analyze the characteristic polynomial associated to an ellipsoid and another quadric in the context of the contact detection problem. We obtain a necessary and sufficient
condition for an efficient method ...
The Auslander-Reiten quiver of the category of m−periodic complexes
(Elsevier, 2024-05)
[Abstract]: Let A be an additive k−category and C≡m(A) be the category of m−periodic
complexes. For any integer m > 1, we study conditions under which the compression
b
functor Fm : C (A) → C≡m(A) preserves or reflects ...
On the Degree in Categories of Complexes of Fixed Size
(Springer, 2019-02-01)
[Abstract]: We consider Λ an artin algebra and n ≥ 2. We study how to compute the left and right degrees of irreducible morphisms between complexes in a generalized standard Auslander-Reiten component of Cn(proj Λ) with ...
Classification of the relative positions between a small ellipsoid and an elliptic paraboloid
(Elsevier, 2019-06)
[Abstract]: We classify all the relative positions between an ellipsoid and an elliptic paraboloid when the ellipsoid is small in comparison with the paraboloid (small meaning that the two surfaces cannot be tangent at two ...
Graphs with isolation number equal to one third of the order
(Elsevier B.V., 2024-05)
[Absctract]: A set D of vertices of a graph G is isolating if the set of vertices not in D and with no
neighbor in D is independent. The isolation number of G, denoted by ι(G), is the minimum
cardinality of an isolating ...
Isolation Number versus Domination Number of Trees
(MDPI, 2021-06)
[Abstract] If 𝐺 = (Vɢ,Eɢ) is a graph of order n, we call 𝑆 ⊆ Vɢ an isolating set if the graph induced by Vɢ − Nɢ[𝑆] contains no edges. The minimum cardinality of an isolating set of 𝐺 is called the isolation number of ...
