Representation theory of order-related monoids of partial functions as locally trivial category algebras
Itamar Stein
In this paper we study the representation theory of three monoids of partial functions on an -set. The monoid of all order-preserving functions (i.e., functions satisfying $f(x)…
Generating subgraphs in chordal graphs
Vadim E. Levit, David Tankus
A graph is well-covered if all its maximal independent sets are of the same cardinality. Assume that a weight function is defined on its vertices. Then is -well-cove…
Densely locally minimal groups
Wenfei Xi, Dikran Dikranjan, Menachem Shlossberg +1
We study locally compact groups having all dense subgroups (locally) minimal. We call such groups densely (locally) minimal. In 1972 Prodanov proved that the infinite compact abeli…
Stability of a topological insulator: interactions, disorder and parity of Kramers doublets
V. Kagalovsky, A. L. Chudnovskiy, I. V. Yurkevich
We study stability of multiple conducting edge states in a topological insulator against all multi-particle perturbations allowed by the time-reversal symmetry. We model a system a…
