Weighted analytic regularity for the integral fractional Laplacian in polygons

Markus Faustmann, Carlo Marcati, Jens Markus Melenk +1

We prove weighted analytic regularity of solutions to the Dirichlet problem for the integral fractional Laplacian in polygons with analytic right-hand side. We localize the problem…

Spurious Quasi-Resonances in Boundary Integral Equations for the Helmholtz Transmission Problem

Ralf Hiptmair, Andrea Moiola, Euan A. Spence

We consider the Helmholtz transmission problem with piecewise-constant material coefficients, and the standard associated direct boundary integral equations. For certain coefficien…

On Bayesian data assimilation for PDEs with ill-posed forward problems

Samuel Lanthaler, Siddhartha Mishra, Franziska Weber

We study Bayesian data assimilation (filtering) for time-evolution PDEs, for which the underlying forward problem may be very unstable or ill-posed. Such PDEs, which include the Na…

Weighted analyticity of Hartree-Fock eigenfunctions

Yvon Maday, Carlo Marcati

We prove analytic-type estimates in weighted Sobolev spaces on the eigenfunctions of a class of elliptic and nonlinear eigenvalue problems with singular potentials, which includes…

The higher order fractional Calderón problem for linear local operators: uniqueness

Giovanni Covi, Keijo Mönkkönen, Jesse Railo +1

We study an inverse problem for the fractional Schrödinger equation (FSE) with a local perturbation by a linear partial differential operator (PDO) of order smaller than the order…

On the conservation of energy in two-dimensional incompressible flows

S. Lanthaler, S. Mishra, C. Parés-Pulido

We prove the conservation of energy for weak and statistical solutions of the two-dimensional Euler equations, generated as strong (in an appropriate topology) limits of the underl…

Regularity properties for solutions of infinite dimensional Kolmogorov equations in Hilbert spaces

Adam Andersson, Mario Hefter, Arnulf Jentzen +1

In this article we establish regularity properties for solutions of infinite dimensional Kolmogorov equations. We prove that if the nonlinear drift coefficients, the nonlinear diff…

Statistical solutions of hyperbolic conservation laws I: Foundations

Ulrik Skre Fjordholm, Samuel Lanthaler, Siddhartha Mishra

We seek to define statistical solutions of hyperbolic systems of conservation laws as time-parametrized probability measures on -integrable functions. To do so, we prove the equ…

Sparse Deterministic Approximation of Bayesian Inverse Problems

Ch. Schwab, A. M. Stuart

We present a parametric deterministic formulation of Bayesian inverse problems with input parameter from infinite dimensional, separable Banach spaces. In this formulation, the for…
