报告摘要：Given a local field F, define a reductive G over F. Suppose that there exists an involution on G such that the fixed points form another reductive group, denoted by H. Then G/H is a symmetric pair. How to describe the space S(G/H), i.e., those smooth representations Pi of G restricted to H containing the trivial character as a quotient, is so called the relative Langlands program. They are related to the nonvanishing property of certain L-functions at some special points. In this talk, we will give a brief introduction, including the Langlands functoriality conjecture, the multiplicities problems and the special value of certain L-functions, based on the examples. In particular, we will focus on the Galois involution and the PTB pairs.
