## Feynman-Maslov calculus of noncommuting operators and application to adiabatic and homogenization problems

Prof. Dr. Sergey Dobrokhotov talk

Speaker invited by: Prof. Dr. Thomas Kappeler

**Date:** 28.02.19 **Time:** 14.00 - 15.00 **Room:** Y27H12

We discuss some ideas and elementary useful formulas from the Feynman-Maslov calculus of noncommuting operators (pseudodifferential operators with a small parameter) and their applications to adiabatic problems. As example we consider the problems from physics of low-dimensional structures (quantum waveguides) and homogenization problems for partial differential equations with rapidly oscillating coefficients.
