摘要
The aim of the article is to show the invalidity of the Strichartz estimate for the free Schrodinger equation associated with the Ornstein-Uhlenbeck operator L = -1/2 Delta+ < x, del > in R-n. As a consequence we obtain a negative answer to the Fourier-Hermite restriction problem associated with the normalized Hermite polynomials for a discrete surface in Z x N-0(n).
