This article continues a prior investigation of the authors with the goal of extending characterization results of convolutional tight frames from the context of cyclic groups to general finite abelia...
Stationary Wigner Equation with In ow Boundary Conditions: Will a Symmetric Potential Yield a Symmetric Solution
Wigner equation In ow boundary conditions Well-posedness.
2014/9/26
Based on the well-posedness of the stationary Wigner equation with in
ow bound-ary conditions given in [1], we prove without any additional prerequisite conditions
that the solution of the Wigner eq...

Logarithmic potential beta-ensembles Feynman graphs
2010/12/14
We present the diagrammatic technique for calculating the free energy of the matrix eigenvalue
model (the model with arbitrary power β by the Vandermonde) to all orders of 1/N expansion in
the case ...
Towards an Lp potential theory for sub-Markovian semigroups: kernels and capacities
nonlinear potential theory $(r,p)$-capacity Bessel potential space gamma-transform sub-Markovian semigroup
2007/12/12
We study in fairly general measure spaces $(X,\mu)$ the (non-linear) potential theory of $L^p$ sub-Markovian semigroups which are given by kernels having a density with respect to the underlying measu...
