Talk by Alexander Dicke
On April 6th, 2022, Alexander Dicke (TU Dortmund) gave a talk about "Observability from sensor sets with decaying density" as part of the research seminar Analysis of the FernUniversität in Hagen.
We show observability for a whole class of parabolic equations on $R^d$ from sensor sets with decaying density. The proof is based on spectral inequalities for the (partial) harmonic oscillator and corresponding dissipation estimates. The presented results are based on joint work with Albrecht Seelmann and Ivan Veselic.
