Asymptotically optimal cubature formulas on manifolds for prefixed weights
Martin Ehler, Ujué Etayo, Bianca Gariboldi +2
We propose a new extension of the proof of the Korevaar-Meyers conjecture by Bondarenko, Radchenko and Viazovska for cubature formulas with prefixed weights (we fix different weigh…
A Randomized Multivariate Matrix Pencil Method for Superresolution Microscopy
Martin Ehler, Stefan Kunis, Thomas Peter +1
The matrix pencil method is an eigenvalue based approach for the parameter identification of sparse exponential sums. We derive a reconstruction algorithm for multivariate exponent…
Prony's method under an almost sharp multivariate Ingham inequality
Stefan Kunis, H. Michael Möller, Thomas Peter +1
The parameter reconstruction problem in a sum of Dirac measures from its low frequency trigonometric moments is well understood in the univariate case and has a sharp transition of…
Cubatures on Grassmannians: moments, dimension reduction, and related topics
Anna Breger, Martin Ehler, Manuel Graef +1
We briefly explain the use of cubature points on Grassmannians in numerical analysis.
A multivariate generalization of Prony's method
Stefan Kunis, Thomas Peter, Tim Roemer +1
Prony's method is a prototypical eigenvalue analysis based method for the reconstruction of a finitely supported complex measure on the unit circle from its moments up to a certain…
