On the subdirect product of graph bundles
Yanga Bavuma, Francesco G. Russo, Stefano Spessato
The subdirect product of two finite groups and is defined as a subgroup of the direct product , which is a well-known notion in finite group theory. While it is…
Godsil-McKay switchings for gain graphs
Matteo Cavaleri, Alfredo Donno, Stefano Spessato
We introduce a switching operation, inspired by the Godsil-McKay switching, in order to obtain pairs of -cospectral gain graphs, that are gain graphs cospectral with respect to…
Uniform homotopy invariance of Roe Index of the signature operator
Stefano Spessato
In this paper we study the Roe index of the signature operator of manifolds of bounded geometry. Our main result is the proof of the uniform homotopy invariance of this index. In o…
Lipschitz-homotopy invariants:-cohomology, Roe index and -class
Stefano Spessato
In this thesis we talk about lipschitz-homotopy invariants for manifolds of bounded geometry. There are three main results: the first one is the definition of a controvariant funct…
A pullback functor for reduced and unreduced -cohomology
Stefano Spessato
In this paper we study the reduced and unreduced -cohomology groups of manifolds of bounded geometry and their behavior under uniform maps. A \textit{uniform map} is a uni…
