    • Rigidity of weighted Einstein smooth metric measure spaces 

      Brozos-Vázquez, Miguel; Mojón Álvarez, Diego (Elsevier, 2024-01)
      [Abstract] We study the geometric structure of weighted Einstein smooth metric measure spaces with weighted harmonic Weyl tensor. A complete local classification is provided, showing that either the underlying manifold is ...

    • Graphs with isolation number equal to one third of the order 

      Lemańska, Magdalena; Mora, Mercè; Souto Salorio, María José (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 ...

    • The Auslander-Reiten quiver of the category of m−periodic complexes 

      Chaio, Claudia; González Chaio, Alfredo; Pratti, Isabel; Souto Salorio, María José (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 

      Chaio, Claudia; Pratti, Isabel; Souto Salorio, María José (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 

      Brozos-Vázquez, Miguel; Pereira Sáez, María José; Souto Salorio, María José; Tarrío-Tobar, Ana D. (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 ...
