A new REM conjecture

We introduce here a new universality conjecture for levels of random Hamiltonians, in the same spirit, as the local REM conjecture made by S. Mertens and H. Bauke. We establish our conjecture for a wide class of Gaussian and non-Gaussian Hamiltonians, whic ...

Performance of Sigma-Delta Quantizations in Finite Frames

In this paper, we consider sigma-delta (SD) quantization of geometrically uniform (GU) finite frames. In the first part, we prove that under some conditions, the variant I and II permutation modulation (PM) codes, first introduced by Slepian (1968, 1965), ...

A law of the iterated logarithm for fractional Brownian motions

Thomas Mountford

We show that for a class of Gaussian processes indexed by one dimensional time, the local times obey the behavior conjectured by Xiao. ...
