Spectral analysis and best decay rate of the wave propagator on the tadpole graph

Kaïs Ammari, Rachid Assel, Mouez Dimassi

We consider the damped wave semigroup on the tadpole graph $R$ . We first give a meticulous spectral analysis, followed by a judicious decomposition of the resolvent's ke…

Spectral analysis and stabilization of the dissipative Schrödinger operator on the tadpole graph

Kaïs Ammari, Rachid Assel

We consider the damped Schrödinger semigroup $e^{- i t \frac{d ^{2}}{d x ^{2}}}$ on the tadpole graph $R$ . We first give a careful spectral analysis and an appropriate decomposit…
