Abstract: Let G be a complex reductive Lie group with Lie algebra g and maximal compact subgroup K. Given a finite length (g,K)-module V, we want to understand the structure of its restriction to K. Then we decompose this restriction as the sum of irreducible representations of K with finite multiplicities. This gives us the concept of multiplicity functions.

We will also introduce the Lusztig-Vogan bijection from the point of view of Harish-Chandra modules. At last, we give an explicit combinatorial description for this bijection in some simple cases.
