abstract:
Let $G$ be a connected reductive group over $\Bbb{Q}$. In this paper, we give the stabilization of the local trace formula. In particular, we construct the explicit form of the spectral side of the stable local trace formula in the Archimedean case, when one component of the test function is cuspidal. We also give the multiplicity formula for discrete series. At the same time, we obtain the stable version of $L^2$-Lefschetz number formula.
