Hardy spaces for semigroups with Gaussian bounds
Jacek Dziubański, Marcin Preisner
Let T_t=e^{-tL} be a semigroup of self-adjoint linear operators acting on L^2(X,mu), where (X,d mu) is a space of homogeneous type. We assume that T_t has an integral kernel T_t(x,…

Hardy spaces for Bessel-Schrödinger operators
Edyta Kania, Marcin Preisner
Consider the Bessel operator with a potential on L^2((0,infty), x^a dx), namely Lf(x) = -f"(x) - a/x f'(x) + V(x)f(x). We assume that a>0 and V\in L^1_{loc}((0,infty), x^a dx) is a…
