Title:Spectral coincidence of transition operators, automata groups and BBS in tropical geometry
Seminar:GAP Seminar
Speaker:Tsuyoshi Kato, Kyoto University
Abstract:
I will speak on our discovery of a spectral coincidence of Markov operators between the lamplighter group and the box-ball system. The former appears in group theory and the latter is the automaton of the KdV equation in in finite integrable systems, passing through tropical geometry. This is joint work with S. Tsujimoto and A. Zuk.
