Asymptotic estimates of solution to damped fractional wave equation

M Wang, D Fan - Journal of Inequalities and Applications, 2024 - Springer
It is known that the damped fractional wave equation has the diffusive structure as t→∞. Let
u (t, x)= e− t cosh (t L) f (x)+ e− t sinh (t L) L (f (x)+ g (x)) be the solution of the Cauchy …
