Riesz transform characterization of Hardy spaces associated with Schr\"odinger operators with compactly supported potentials

open access: yes, 2009
Let L=-\Delta+V be a Schr\"odinger operator on R^d, d\geq 3. We assume that V is a nonnegative, compactly supported potential that belongs to L^p(R^d), for some p>d/2. Let K_t be the semigroup generated by -L.

On the restricted summability of the multi-dimensional Vilenkin-Cesàro means

open access: yes, 2017
The properties of the maximal operator of the (C,α) -means (α = (α1, . . . ,αd) ) of the multi-dimensional Vilenkin-Fourier series are discussed, where the set of indices is inside a cone-like set.

Predictability on finite horizon for processes with exponential decrease of energy on higher frequencies

open access: yes, 2009
The paper presents sufficient conditions of predictability for continuous time processes in deterministic setting. We found that processes with exponential decay on energy for higher frequencies are predictable in some weak sense on some finite time ...
