New definitions of decay indicators and critical exponent for fractional semi-linear structurally damped evolution equations on the Heisenberg group
Duc An Phan, The Anh Cung
In this paper, we introduce the lower and upper decay indicators and the associated decay character on the Heisenberg group. These notions are used to derive decay estimates for th…

Duc An Phan, The Anh Cung, Trung Loc Tang
In this paper, we study the semilinear wave equations with effective time-dependent damping and a time…
