Mehler’s formula and functional calculus

  • Nicolas LernerEmail author


We show that Mehler’s formula can be used to handle several formulas involving the quantization of singular Hamiltonians. In particular, we diagonalize in the Hermite basis the Weyl quantization of the characteristic function of several domains of the phase space.
