First-order aspects of Artin groups

Alberto Cassella, Gianluca Paolini, Giovanni Paolini

We prove several results on the model theory of Artin groups, focusing on Artin groups which are ``far from right-angled Artin groups''. The first result is that if i…

Groups of p-absolute Galois type that are not absolute Galois groups

Simone Blumer, Alberto Cassella, Claudio Quadrelli

Let p be a prime. We study pro-p groups of p-absolute Galois type, as defined by Lam-Liu-Sharifi-Wake-Wang. We prove that the pro-p completion of the right-angled Artin group assoc…

Right-angled Artin groups and enhanced Koszul properties

Alberto Cassella, Claudio Quadrelli

Let F be a finite field. We prove that the cohomology algebra with coefficients in F of a right-angled Artin group is a strongly Koszul algebra for every finite graph . Moreover…
