ABSTRACT:
The quantum theory on graphs is studied where the dynamics is given by Laplace operators. The resulting scattering theory is studied. The S-Matrix has a Gutzwiller-Selberg type path-representation. This structure of the S-Matrix allows to find a solution to the Traveling Salesman Problem.
BIO:
Robert Schrader received his diploma in theoretical physics in Hamburg and his Ph.D. at the ETH Zurich (Switzerland). He was a post doc at Harvard and Princeton. Since 1973 he has been a Professor of Theoretical Physics at Freie Universität Berlin. His current fields of interest are mathematical physics, quantum field theory, topological quantum field theory, statistical mechanics and quantum computation.
