DESCRIPTION:Speakers: Alexander Marynych\n\nThe standard convex closed hul
l of a subset of $\\mathbb{R}^d$ is defined as the intersection of all ima
ges\, under the action of a group of rigid motions\, of a half-space conta
ining the given set. We propose\na generalisation of this classical notion
\, that we call a $(K\,\\mathbb{H})$-hull\, and which is obtained from the
above construction by replacing a half-space with some other convex close
d subset $K$ of the Euclidean space\, and a group of rigid motions by a su
bset $\\mathbb{H}$ of the group of invertible affine\ntransformations. The
above construction encompasses and generalises several known models in co
nvex stochastic geometry and allows us to gather them under a single umbre
lla. The talk is based on recent\nworks by Kalbuchko\, Marynych\, Temesvar
i\, ThÃ¤le (2019)\, Marynych\, Molchanov (2021) and Kabluchko\,\nMarynych\
, Molchanov (2022+).\n\nhttps://indico.math.cnrs.fr/event/8950/
