(Ir)regular singularities and Quantum Field Theory
(Ir)regular singularities and Quantum Field Theory
July 8-11, 2019
Lisbon University, Department of Mathematics
The main theme of the conference is the (generalised) monodromy of meromorphic connections, and its links to quantum field theory. These include the ODE/IM (or ODE/IQFT) correspondence, the relation between opers and the Bethe Ansatz equations, the analysis of anharmonic oscillators in the realm of PT symmetric and exactly solvable quantum mechanics, the relation between Painlevé equations and conformal field theories.
This will be a great occasion to celebrate the 50th anniversary of the paper “Anharmonic Oscillator” by C. Bender and T. Wu and the 20th anniversary of the discovery of the ODE/IM correspondence.
