$L^2$ norms of Whittaker vectors and zeros of Intertwining operators

For $\mu,\nu\in \mathbb{C}^2$ we denote $I(\mu,\nu)$ to be the principal series of $\mathrm{GL}_2(\mathbb{Q}_p)$ induced from $|.|^\mu\otimes |.|^\nu$. For $s=\mu-\nu$ one defines the standard ...

Explicit description of the Plancherel measure for $GL_n(\mathbb{R})$

Let $G:=\mathrm{GL}_n(\mathbb{R})$ and $f\in C_c^\infty(G)$. One can uniquely determine the Plancherel measure $d\mu_p$ on $\hat{G}$, the unitary (actually tempered) dual of $G$, by the equation $$f(g)...

Is there an analysis theorem analogous to Kuznetsov/Petersson trace formula?

I am thinking about general differential operator acts on a compact manifold. Is there something similar to Kuznetsov trace formula? For example, let $f_i $ be the eigenfunctions of an operator $D$, ...
