SUMMARY:On generalised presentations over topological groups - Brita Nucin
 kis (Royal Holloway)
DTSTART:20260313T134500Z

CONTACT:Francesco Fournier-Facio
DESCRIPTION:I will present a procedure that turns certain abstract  presen
 tations\, such as those for surface groups\, Thompson groups\, and Artin g
 roups into topological groups with a prescribed open subgroup. These all s
 hare some topological properties depending on the chosen open subgroup. Fo
 r studying cohomological finiteness conditions\, we concentrate on totally
  disconnected locally compact RAAGs  and present a generalisation of the S
 alvetti complex for these groups. \n\nThis is joint work with Ilaria Caste
 llano\, Bianca Marchionna and Yuri Santos Rego.
