Talk by Vyacheslav Pivovarchik

On August 24th, 2022, Prof. Dr. Vyacheslav Pivovarchik (Odessa) gave a talk about "On cospectral quantum graphs with Dirichlet conditions at pendant vertices" as part of the research seminar Analysis of the FernUniversität in Hagen. This lecture is partially supported by the COST action Mathematical models for interacting dynamics on networks.


Show Abstract

We prove that in case of the Dirichlet boundary conditions at the pendant vertices there are no cospectral trees with the number of vertices less or equal to 8. We also show all the cospectral trees with 9 vertices.
