Creation and annihilation operators for anharmonic oscillators

Research output: Contribution to journal › Article › peer-review

Abstract

Positive elliptic operators from the Helffer-Robert classes of pseudodifferential operators on the line can be approximately factored as products of creation and annihilation operators. Operators of anharmonic oscillators belong to these classes.
