Asymptotics and Scattering for Critically Weakly Hyperbolic and Singular Systems
Bolys Sabitbek, Arick Shao
We study a very general class of first-order linear hyperbolic systems that both become weakly hyperbolic and contain lower-order coefficients that blow up at a single time …

Global existence and blow-up of solutions to the double nonlinear porous medium equation
Bolys Sabitbek, Berikbol Torebek
In this study, we examine a double nonlinear porous medium equation subject to a novel nonlinearity condition within a bounded domain. First, we introduce the blow-up solution for…
