WebApr 1, 2000 · Hermite polynomials also play an important role in stochastic integrals, Central Limit Theorems and in L2 theory: they are orthogonal with respect to their dual polynomials (1.2) H e ν (x,V)=φ (x,V) −1 (−∂/∂z) ν φ (Vz,V) at z=V −1 x, in the sense that (1.3) ∫ H e j (x,V) He k (x,V)φ (x,V) d x=j! if j=k and 0 otherwise where j != j1 !⋯ jp !. One can define the Hermite functions (often called Hermite-Gaussian functions) from the physicist's polynomials: Since these functions contain the square root of the weight function and have been scaled appropriately, they are orthonormal: The Hermite functions are closely related to the Whittaker function (Whittaker …
