Let G be a real semi-simple Lie group. Let A be an arithmetic subgroup of the
group G. Suppose that F is a finite-dimensional representation of G. One of
the objects of interest is the cohomology group H (A, F). In ...
Let F be a totally real number field, r = [F : Q], and N be an
integral ideal. Let Ak(N, ω) be the space of holomorphic Hilbert cusp forms
with respect to K1(N), weight k = (k1, ..., kr) with kj > 2, kj even for all
j ...
Denote the Siegel upper half space as $$\mathbb{H}_2=\{X+iY \in M_2(\mathbb{C})~|~ X=X^t, Y=Y^t,Y>0\}. $$
A holomorphic function $F:\mathbb{H}_2 \rightarrow \mathbb{C}$ is called a Siegel modular form of weight $k$, if ...
