Global in-time rough large data solution to complex-valued semilinear damped evolution equations
Wenhui Chen, Michael Reissig
We study the semilinear Cauchy problem for complex-valued damped evolution equations \begin{align*} \partial_t^2u+(-Î)^Ïu+(-Î)^δ\partial_tu=u^p,\ \ u(0,x)=u_0(x),\ \partial_tu(…

Evolution models with time-dependent coefficients in friction and viscoelastic damping terms
Halit Sevki Aslan, Michael Reissig
We study the following Cauchy problem for the linear wave equation with both time-dependent friction and time-dependent viscoelastic damping: \begin{equation} \label{EqAbstract}\ta…

Critical curve for a weakly coupled system of semi-linear -evolution equations with different damping types
Dinh Van Duong, Tuan Anh Dao, Michael Reissig
In this paper, we would like to consider the Cauchy problem for a weakly coupled system of semi linear evolution equations with different damping mechanisms for any ,…
