In this paper, we study diffusion phenomena for the wave equation with structural damping utt− Δ u+ 2 a (− Δ) σ ut= 0, u (0, x)= u 0 (x), ut (0, x)= u 1 (x), with a> 0 and σ∈(0, 1/2). We …

In this article, we analyze a spatio-temporally nonlocal nonlinear parabolic equation. First, we validate the equation by an existence-uniqueness result. Then, we show that blowing-up …
In this paper we study the global existence of small data solutions to utt−△ u+ 2 a (−△) σ ut=| u| p, u (0, x)= u 0 (x), ut (0, x)= u 1 (x), where a> 0, σ∈(0, 1/2] and p> 1. Assuming small …
