Higher order logarithms of Bessel operators and an extension problem

Jorge J. Betancor, Estefanía. Dalmasso, Juan C. Fariña +1

We consider the Bessel operator defined by \[ B_λ=-\frac{d^2}{dx^2}+\frac{λ^2-1/4}{x^2}, \] on $(0, \infty)$ , with $λ > - 1$ . We study the fractional power $B_{λ}^{s}$ , $s \in (- 1, 1)$ , $s\n…

A $T 1$ criterion for Schrödinger-Calderón-Zygmund operators with exponential decay

Estefanía Dalmasso, Gabriela R. Lezama, Marisa Toschi

We establish the boundedness of exponential Schrödinger-Calderón-Zygmund operators on weighted $B M O_{ρ}^{α} (w)$ spaces via a $T 1$ criterion, where the weights belong to classes that ca…

On $m$ -order logarithmic Schrödinger operator

Jorge J. Betancor, Estefanía Dalmasso, Pablo Quijano +1

In this paper we study the logarithm of order $m$ of the Schrödinger operator $L_{V}$ in $R^{d}$ , for certain nonnegative potentials $V$ . First, the operator $\log^m\m…

Logarithmic Schrödinger operators

Jorge J. Betancor, Estefanía Dalmasso, Juan C. Fariña +1

In this paper we consider the Schrödinger operator $L_{V} = - Δ + V$ in $R^{d}$ with a non negative potential $V$ , and $V \neq \equiv 0$ . We define the logarithmic Schrödin…
