Stochastic regularity of general quadratic observables of high frequency waves
Gabriela Malenova, Olof Runborg
We consider the wave equation with uncertain initial data and medium, when the wavelength of the solution is short compared to the distance traveled by the wave. We a…
A Sparse Stochastic Collocation Technique for High-Frequency Wave Propagation with Uncertainty
Gabriela Malenova, Mohammad Motamed, Olof Runborg +1
We consider the wave equation with highly oscillatory initial data, where there is uncertainty in the wave speed, initial phase and/or initial amplitude. To estimate quantities of…
On the Spectral Gap of a Quantum Graph
James B. Kennedy, Pavel Kurasov, Gabriela Malenova +1
We consider the problem of finding universal bounds of "isoperimetric" or "isodiametric" type on the spectral gap of the Laplacian on a metric graph with natural boundary condition…
Spectral gap for quantum graphs and their connectivity
Pavel Kurasov, Gabriela Malenova, Sergey Naboko
The spectral gap for Laplace operators on metric graphs is investigated in relation to graph's connectivity, in particular what happens if an edge is added to (or deleted from) a g…
