On the persistence of spatial analyticity for the Beam Equation

Tamirat T. Dufera, Sileshi Mebrate, Achenef Tesfahun

Persistence of spatial analyticity is studied for solution of the beam equation $u_{tt} + (m + Δ^{2}) u + ∣ u ∣^{p - 1} u = 0$ on $R^{n} \times R$ . In particular,…

Improved Lower Bound for the Radius of Analyticity of Solutions to the fifth order KdV-BBM model

Tamirat T. Dufera, Sileshi Mebrate, Achenef Tesfahun

We show that the uniform radius of spatial analyticity $σ (t)$ of solutions at time $t$ to the fifth order KdV-BBM equation cannot decay faster than $1/ t$ for large $t$ , giv…
