Crossing Matrices of Positive Braids
Mauricio Gutierrez, Zbigniew Nitecki
The crossing matrix of a braid on strands is the integer matrix with zero diagonal whose entry is the algebraic number (positive minus negative) of crossings…
A generating set for the automorphism group of a graph product of abelian groups
Luis Corredor, Mauricio Gutierrez
We find a set of generators for the automorphism group of a graph product of finitely generated abelian groups entirely from a certain labeled graph. In addition, we find generator…
On the automorphisms of a graph product of abelian groups
Mauricio Gutierrez, Adam Piggott, Kim Ruane
We study the automorphisms of a graph product of finitely-generated abelian groups W. More precisely, we study a natural subgroup Aut* W of Aut W, with Aut* W = Aut W whenever vert…
Rigidity of graph products of abelian groups
Mauricio Gutierrez, Adam Piggott
We show that if is a group and has a graph-product decomposition with finitely-generated abelian vertex groups, then has two canonical decompositions as a graph product…
