Null-controllability and control cost estimates for the heat equation on unbounded and large bounded domains
Michela Egidi, Ivica Nakić, Albrecht Seelmann +3
We survey recent results on the control problem for the heat equation on unbounded and large bounded domains. First we formulate new uncertainty relations, respectively spectral in…

Laplace-eigenfunctions on the torus with high vanishing order
Matthias Täufer
We use the sum-of-squares theorem from number theory to construct eigenfunctions of the Laplacian on the -dimensional torus, , which vanish to any prescribed order at…
