Uncertainty principles and lower bounds for Schrödinger operators
Albrecht Böttcher, Peter Stollmann, Martin Tautenhahn
We prove that two different abstract quantitative uncertainty principles are equivalent to the strict positivity of the associated abstract Schrö\-din\-ger operators. We also disc…

Florentin Münch, Christian Seifert, Peter Stollmann +1
We consider linear control problems for the heat equation of the form , , where is the weighted Laplacian on…
