Hölder damping for fractional wave equations

Jian Wang, Ruoyu P. T. Wang

For fractional wave equations with low Hölder regularity damping, we establish quantitative energy decay rates for their solutions when the geometric control condition holds. The e…

Stabilisation of Waves on Product Manifolds by Boundary Strips

Ruoyu P. T. Wang

We show that a transversely geometrically controlling boundary damping strip is sufficient but not necessary for $t^{- 1/2}$ -decay of waves on product manifolds. We give a general s…

Sharp Polynomial Decay for Waves Damped from the Boundary in Cylindrical Waveguides

Ruoyu P. T. Wang

We study the decay of global energy for the wave equation with Hölder continuous damping placed on the $C^{1, 1}$ -boundary of compact and non-compact waveguides with star-shaped cro…
