摘要
If F is a non-Archimedean local field, local class field theory induces a canonical bijection between the characters of the multiplicative group of F and the characters of the Weil group of F . For a positive integer n , it turns out that the $n$-dimension analogy of the characters of $F^{times}$ is irreducible smoothrepresentations of GL(n,F).
The local Langlands conjecture for GL(n) predicts the existence of a canonical bijection between such objects and the n -dimensional semisimple representations of the Weil group of F , thus it generalizes local class field theory. This conjecture has now been completely proved.
The goal of these lectures is to give a brief introduction to the local constrction of Langlands correspondence for GL(2) , given by Bushnell and Henniart recently. For the sake of simplicity, we avoid the tortuous case of p=2 ( p is the characteristic of the residue field of F), i.e.,we consider here only the tame case $pneq2$. The lectures will also contain some backgrounds.
