The workshop will survey various important and active areas of the representation theory of finite and algebraic groups, and introduce the audience to several basic open problems in the area. It will ...
Exponential Convergence Rates of Second Quantization Semigroups and Applications
Convergence rate tail norm entropy second quantization L´ evy processes
2011/2/28
Exponential convergence rates in the L2-tail norm and entropy are characterized for the second quantization semigroups by using the corresponding base Dirichlet form. This supplements the well known r...

We prove the following sharp upper bound for the gradient of the Neumann semigroup Pt on a d-dimensional compact domain with boundary either C2- smooth or convex: k∇Ptk1→∞ ≤c t(d+1)/2
, t > 0,...
Non-time-homogeneous Generalized Mehler Semigroups and Applications
Non-homogeneous generalized Mehler semigroup additive process

A non-time-homogeneous generalized Mehler semigroup on a real sep-arable Hilbert space H is defined through ps,tf(x) = Z H f(U(t, s)x + y) μt,s(dy), t ≥ s, x ∈ H,for every bounded measurable function ...

Heisenberg group Sobolev inequalities Poincar\'e inequalities best constants
2007/12/11
Let $f$ be in the localized nonisotropic Sobolev space $W_{\rm loc}^{1,p}(\Bbb H^n) $ on the $n$-dimensional Heisenberg group $\Bbb H^n=\Bbb C^n\times \Bbb R$, where $1\leq p and $Q=2n+2$ is the h...
