Regularity estimates in Hölder spaces for Schrödinger operators via a T1 theorem
Tao Ma, P. R. Stinga, J. L. Torrea +1
We derive Hölder regularity estimates for operators associated with a time independent Schrödinger operator of the form . The results are obtained by checking a certain condi…

Regularity properties of Schrödinger operators
Tao Ma, P. R. Stinga, J. L. Torrea +1
Let L be a Schrödinger operator of the form L=-Δ+V, where the nonnegative potential V satisfies a reverse Hölder inequality. Using the method of L-harmonic extensions we study regu…

Fractional Vector-Valued Littlewood-Paley-Stein Theory for Semigroups
José L. Torrea, Chao Zhang
We consider the fractional derivative of a general Poisson semigroup. With this fractional derivative we define the generalized fractional Littlewood-Paley -function for semigro…
