On Diophantine properties for values of Dedekind zeta functions
Jerson Caro, Fabien Pazuki, Riccardo Pengo
We study the Northcott and Bogomolov property for special values of Dedekind -functions at real values . We prove, in particular, that the Bogomolov property…

Irreducibility criteria for the preimages of a transverse variety under endomorphisms of products of elliptic curves
Riccardo Pengo, Evelina Viada
We provide two different proofs of an irreducibility criterion for the preimages of a transverse subvariety of a product of elliptic curves under a diagonal endomorphism of suffici…

Spanning trees in -covers of a finite graph and Mahler measures
Riccardo Pengo, Daniel Vallières
Using the special value at of Artin-Ihara -functions, we associate to every -cover of a finite connected graph a polynomial which we call the \emph{Ihara polyn…
