Boundary-Weighted Fourier Inequalities for Convex Domains
Konstantinos Bampouras, Karl-Mikael Perfekt
We consider the natural family of Fourier inequalities for the Paley--Wiener space , consisting of -functions with Fourier support in a convex set $Ω\subset…
Comparison inequalities for Dirichlet-to-Neumann maps
Denis S. Grebenkov, Michael Levitin, Karl-Mikael Perfekt +1
We prove comparison inequalities for Dirichlet-to-Neumann maps corresponding to different non-positive Helmholtz parameters. For convex domains our bounds are sharp, and the result…
Recovering Product BMO from Schatten Hankel operators
Konstantinos Bampouras, Karl-Mikael Perfekt
We prove that if a small Hankel operator on the product Hardy space belongs to some Schatten class , , then it has a symbol in product BMO. In other words, the con…
Characterizations for arbitrary Békollé-Bonami weights
Carlos Mudarra, Karl-Mikael Perfekt
We precisely characterize the relationships between the reverse Hölder inequality, the Fujii-Wilson condition, the Békollé-Bonami condition, the …
The Complex-Scaled Half-Space Matching Method
Anne-Sophie Bonnet-Ben Dhia, Simon N. Chandler-Wilde, Sonia Fliss +3
The Half-Space Matching (HSM) method has recently been developed as a new method for the solution of 2D scattering problems with complex backgrounds, providing an alternative to Pe…
Plasmonic eigenvalue problem for corners: limiting absorption principle and absolute continuity in the essential spectrum
Karl-Mikael Perfekt
We consider the plasmonic eigenvalue problem for a general 2D domain with a curvilinear corner, studying the spectral theory of the Neumann--Poincaré operator of the boundary. A li…
