Anders Claesson: Counting interval orders
Time: Thu 2020-02-20 11.00 - 11.50
Lecturer: Anders Claesson, University of Iceland
A partially ordered set is an interval order if it is isomorphic to some set of intervals on the real line ordered by left-to-right precedence. I will give a survey on the enumeration of interval orders (labeled and unlabeled), and their connection to certain classes of permutations.
