Regularity properties of Schrödinger operators

Abstract: Let L be a Schrödinger operator of the form L = −∆ + V , where the nonnegative potential V satisfies a reverse Hölder inequality. Using the method of L-harmonic extensions we study regularity estimates at the scale of adapted Hölder spaces. We give a pointwise description of L-Hölder spaces and provide some characterizations in terms of the growth of fractional derivatives of any order and Carleson measures. Applications to fractional powers of L and multipliers of Laplace transform type developed.2010 Mathema… Show more

“…This same result, only for the case when α + 2s is not an integer, was obtained using pointwise formulas and the Schauder estimates for the Laplacian in [84,85]. In our case the semigroup method permits us to include the case when α + 2s ∈ N. See [29,38,50,69,76,92] for similar proofs in different contexts.…”

“…As already mentioned in the paper by Bongioanni, Harboure and Salinas [6], the BM O α L spaces are the duals of the H p L spaces defined in [12,13,14]. In fact, if s > n and 0 [15], references in [20] and [26].…”

“…2), we can follow the proof of (d) of Proposition 3.6, [10] to show that for V ∈ B q , q ≥ n/2, there is some δ ∈ (0, 1) and N > max{4, 2 log(C 0 + 2 − n)} with C 0 the doubling constant of with respect to the potential V as in (1.1), such that for t > 0 and x ∈ R n ,…”
