SUMMARY:Sebastián Barbieri (LaBRI\, Bordeaux): On the relation between top
 ological entropy and asymptotic pairs
DESCRIPTION:Sebastián Barbieri: WEBINAIRE (lien: https://webconf.lal.cloud
 .math.cnrs.fr/b/pie-hmu-en9 )\n\nAbstract: I will present some results tha
 t state that under certain topological conditions\, any action of a counta
 ble amenable group with positive topological entropy admits off-diagonal a
 symptotic pairs. I shall explain the latest results on this topic and pres
 ent a new\napproach\, inspired from thermodynamical formalism and develope
 d in collaboration with Felipe García-Ramos and Hanfeng Li\, which unifie
 s all previous results and yields new classes of algebraic actions for whi
 ch positive entropy yields non-triviality of their associated homoclinic g
 roup.\nSebastián Barbieri (LaBRI\, Bordeaux)
