Towards topological applications of Laver tables
Speaker: Victoria Lebed (Advanced Mathematical Institute, Osaka City University,Japan)(The talk will be introduced by Valentina Harizanov description of
Richard Laver (1942-2012) work in logic.)
Abstract:
(Joint work with Patrick Dehornoy)
Laver tables are certain finite shelves (i.e., sets endowed with a
binary operation which is distributive with respect to itself). They
originate from set theory and have a profound combinatorial structure.
In this talk I will discuss our dreams regarding potential braid and
knot invariant constructions using Laver tables, and also present some
real results in this direction, such as a detailed description of 2-
and 3-cocycles for Laver tables. The rich structure of the latter
promises interesting topological applications.
