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.
