Fundamental component enhancement via adaptive nonlinear activation functions
Stefan Steinerberger, Hau-Tieng Wu
In many real world oscillatory signals, the fundamental component of a signal might be weak or does not exist. This makes it difficult to estimate the instantaneous frequenc…
Quantum Entanglement and the Growth of Laplacian Eigenfunctions
Stefan Steinerberger
We study the growth of Laplacian eigenfunctions on compact manifolds . Hörmander proved sharp polynomial bounds on which are attai…
A variational principle for Gaussian lattice sums
Laurent Bétermin, Markus Faulhuber, Stefan Steinerberger
We consider a two-dimensional analogue of Jacobi theta functions and prove that, among all lattices with fixed density, the minimal value is maximized by th…
Effective Bounds for the Decay of Schrödinger Eigenfunctions and Agmon bubbles
Stefan Steinerberger
We study solutions of on . Such solutions localize in the `allowed' region and decay exponentially i…
Eigenvector Phase Retrieval: Recovering eigenvectors from the absolute value of their entries
Stefan Steinerberger, Hau-Tieng Wu
We consider the eigenvalue problem where and the eigenvalue is also real . If we are given , and, additionally, th…
A common variable minimax theorem for graphs
Ronald R. Coifman, Nicholas F. Marshall, Stefan Steinerberger
Let be a collection of graphs defined on a common set of vertices but with different edge sets .…
