 d to Funk geometry\n													\n													ABSTRACT /RÉSUMÉ \n\n												The Funk metric is a lesser-kno
 wn cousin of the Hilbert metric in the interior of a convex body\, which i
 n turn generalizes (the Beltrami-Klein model of) hyperbolic geometry. Afte
 r presenting the basics of the Funk metric and some of its surprising prop
 erties\, I will describe several problems in Funk geometry which relate to
 \, generalize and strengthen various well-known theorems and conjectures i
 n convex geometry (such as the Blaschke-Santaló inequality\, the Mahler co
 njecture\, and Schaeffer's dual girth conjecture)\, the Colbois-Verovic vo
 lume entropy conjecture in Hilbert geometry\, polyhedral combinatorics\, a
 nd Minkowski billiards. Partially based on a joint work with Constantin Ve
 rnicos and Cormac Walsh.\n\n												PLACE /LIEU \n													Hybride - CRM\, Salle / Room 534
