Abstract:	Restriction problem is one of the basic problems in representation theory. It studies the decomposition of an irreducible representation of a group when restricted to a subgroup. I will exploit a particular case of the restriction problem: restriction from GL_{2n} to GL_n \times GL_n, and its nonsplit variant. The main theorem is a relation between this restriction problem and the local root numbers. I will end with a potential application to the study of the canonical factorization of linear periods.
