A classification of small operators using graph theory
Terrence Bisson, Jonathan Lopez
Given a real matrix , its operator norm can be defined as We consider a matrix "small" if it has non-negative integer entries and its oper…
Symbolic dynamics and the category of graphs
Terrence Bisson, Aristide Tsemo
Symbolic dynamics is partly the study of walks in a directed graph. By a walk, here we mean a morphism to the graph from the Cayley graph of the monoid of non-negative integers. Se…
Homotopy equivalence of isospectral graphs
Terrence Bisson, Aristide Tsemo
In this paper, we investigate the Quillen model structure defined by Bisson and Tsemo in the category of directed graphs Gph. In particular, we give a precise description of the ho…
A homotopical algebra of graphs related to zeta series
Terrence Bisson, Aristide Tsemo
The purpose of this paper is to develop a homotopical algebra for graphs, relevant to zeta series and spectra of finite graphs. More precisely, we define a Quillen model structure…
Extended powers and Steenrod operations in algebraic geometry
Terrence P. Bisson, Aristide Tsemo
Steenrod operations have been defined by Voedvodsky in motivic cohomology in order to show the Milnor and Bloch-Kato conjectures. These operations have also been constructed by Bro…
