The 2-Adic Valuation of the Order of the All-Ones Class in the Sandpile Group of a Square
Turgay Akyar, Artem Beliakov, Konstantin Delchev +6
Place one grain at every nonsink vertex of the wired square, and let be the order of this operation in the sandpile group. Thus is the least positive …
Many-point tropical relaxation and the Monge--Ampère equation
Nikita Kalinin, Ernesto Lupercio, Higinio Serrano +1
In this paper we prove that a process we call tropical relaxation gives a convergent method for numerically approximating the Monge--Ampère Dirichlet problem on bounded convex plan…
Magnetic Equivariant Graded Brauer Group
Higinio Serrano, Bernardo Uribe
Given a magnetic finite group, we consider the similarity classes of magnetic equivariant central simple graded algebras over the complex numbers. We call this set the magnetic equ…
Magnetic Equivariant K-theory
Higinio Serrano, Bernardo Uribe, Miguel A. Xicoténcatl
We present the fundamental properties of the K-theory groups of complex vector bundles endowed with actions of magnetic groups. In this work we show that the magnetic equivariant K…
Rational magnetic equivariant K-theory
Higinio Serrano, Bernardo Uribe, Miguel A. Xicoténcatl
We introduce the magnetic equivariant K-theory groups as the K-theory groups associated to magnetic groups and their respective magnetic equivariant complex bundles. We restrict th…
Spin Chern number in altermagnets
Rafael Gonzalez-Hernandez, Higinio Serrano, Bernardo Uribe
This work explores the topological properties of altermagnets, a novel class of collinear magnetic materials. We employ equivariant K-theory of magnetic groups and Hamiltonian mode…
