On the Calderón problem for nonlocal Schrödinger equations with homogeneous, directionally antilocal principal symbols
Giovanni Covi, María Ángeles García-Ferrero, Angkana Rüland
In this article we consider direct and inverse problems for -stable, elliptic nonlocal operators whose kernels are possibly only supported on cones and which satisfy the structu…
Runge Approximation and Stability Improvement for a Partial Data Calderón Problem for the Acoustic Helmholtz Equation
María Ángeles García-Ferrero, Angkana Rüland, Wiktoria Zatoń
In this article, we discuss quantitative Runge approximation properties for the acoustic Helmholtz equation and prove stability improvement results in the high frequency limit for…
Exceptional Legendre Polynomials and Confluent Darboux Transformations
María Ángeles García-Ferrero, David Gómez-Ullate, Robert Milson
Exceptional orthogonal polynomials are families of orthogonal polynomials that arise as solutions of Sturm-Liouville eigenvalue problems. They generalize the classical families of…
Strong unique continuation for the higher order fractional Laplacian
María-Ángeles García-Ferrero, Angkana Rüland
In this article we study the strong unique continuation property for solutions of higher order (variable coefficient) fractional Schrödinger operators. We deduce the strong unique…
A Bochner type classification theorem for exceptional orthogonal polynomials
M. Ángeles García-Ferrero, David Gómez-Ullate, Robert Milson
It was recently conjectured that every system of exceptional orthogonal polynomials is related to classical orthogonal polynomials by a sequence of Darboux transformations. In this…
