    In this talk I will introduce the notion of Hochschild (co)homology of categories satisfying certain microlocal conditions. If time permits, I will discuss its application to symplectic geometric quantities such as displacement energy.

Keyword: Hochschild cohomology, displacement energy, microlocal condition.
