DESCRIPTION:Speaker: Patrick Schnider\nhosted by Uli Wagner\nAbstract: The
Ham-Sandwich theorem is a well-known result in geometry. It states that an
y $d$ mass distributions in $\\mathbb{R}^d$ can be simultaneously bisected
by a hyperplane. The result is tight\, that is\, there are examples of $d
+1$ mass distributions that cannot be simultaneously bisected by a single
hyperplane. In this talk we will study the following question: given a con
tinuous assignment of mass distributions to certain subsets of $\\mathbb{R
}^d$\, is there a subset on which we can bisect more masses than what is g
uaranteed by the Ham-Sandwich theorem?We will study two different types of
subsets\, motivated by conjectures by Luis Barba (which we will answer) a
nd Stefan Langerman (which we solve only in a relaxed setting)\, respectiv
ely. Some of the results we also extend to center transversals\, a general
ization of Ham-Sandwich cuts.
