Waldspurger's theorem is a result in number theory, particularly in the area of automorphic forms and representations. It establishes a deep connection between the theory of modular forms and the theory of automorphic representations of reductive groups. Specifically, the theorem describes the relationship between the Fourier coefficients of certain automorphic forms and special values of L-functions.
