Large time behavior and transition from vanishing to spreading regimes for the generalized Burgers-Fisher-KPP equation

Razvan Gabriel Iagar, Ariel SÃ¡nchez

The large time behavior of solutions to the following generalized Burgers-Fisher-KPP equation $\partial_{t} u = u_{xx} + k (u^{n})_{x} + u^{p} - u^{q}, (x, t) \in R \times (0, \infty),$ w…

Blow-up rates and sets for a quasilinear diffusion equation with weighted source

RaÃºl Ferreira, Razvan Gabriel Iagar, Ariel SÃ¡nchez

Blow-up rates are established for general solutions to the quasilinear diffusion equation $\partial_{t} u = I^ u^{m} + ∣ x ∣^{I ¨} u^{p}, (x, t) \in R^{N} \times (0, T),$ in the range of…

Global self-similar solutions for Hardy-HÃ©non equations with linear and quasilinear diffusion

Razvan Gabriel Iagar, Ariel SÃ¡nchez, Erik Sarrion-Pedralva

Global self-similar solutions to the parabolic Hardy-HÃ©non equation $u_{t} = I^ u^{m} + ∣ x ∣^{I ¨} u^{p}, (x, t) \in R^{N} \times (0, \infty),$ are classified in the range of exponents…
