Title: Hormander's generalization of the Fourier restriction problem

Abstract: Hormander 1973 proposed to study a generalized Fourier extension operator, and asked whether the generalized operator satisfies the same L^p bounds as that of the standard Fourier extension operator. Surprisingly, Bourgain 1991 gave a negative answer to Hormander’s question. In this talk, I will discuss a modification of Hormander’s question whose answer may be affirmative. This is a joint work with Hong Wang and Ruixiang Zhang.
