Best rank-k approximations for tensors: generalizing Eckart-Young
Tocino-Sánchez, Alicia
(2020-02-03)
Joint work with Jan Draisma and Giorgio Ottaviani. Given a tensor f in a Euclidean tensor space, we are interested in the critical points of the distance function from f to the set of tensors of rank at most k, which we ... -
Finite sets containing zero are mapping degree sets
Costoya Ramos, María Cristina; Muñoz, Vicente; Viruel-Arbaizar, Antonio Ángel (Elsevier, 2024)
In this paper we solve in the positive the question of whether any finite set of integers, containing 0, is the mapping degree set between two oriented closed connected manifolds of the same dimension. We extend this ... -

Realisability problems in Algebraic Topology
(UMA Editorial, 2020-02-24)Realisability problems in Algebraic Topology are very easy to state and extremely hard to solve. Three classic examples of this are: the realisability of cohomology algebras, proposed by N. E. Steenrod in the 1960s, which ...
