DESCRIPTION:Virtual Artin groups were introduced a few years ago by Bellin
 geri\, Paris\, and Thiel with the aim of generalizing the well-studied str
 ucture of virtual braids to all Artin groups. In this talk\, we will prese
 nt two possible perspectives for studying these groups: an algebraic one a
 nd a topological one. From a topological point of view\, we will explore t
 he construction of K(π\,1) spaces for certain subgroups of virtual Artin 
 groups\, linking them to a famous conjecture and existing constructions.\n
 By an algebraic/group theoretic approach\, we will investigate the rigidit
 y of these groups\, specifically addressing the question of whether they c
 an be decomposed into a direct product of two proper subgroups. The answer
  to this question provides interesting insights into the automorphism grou
 ps of these structures.
