Construction of blow-up solution for 5-dimensional critical Fujita type equation with different blow-up speed

open access: yesJournal of Fixed Point Theory and Applications, 2023
Abstract We are concerned with blow-up solutions of the 5-dimensional energy critical heat equation $u_t=\Delta u + | u |^{\frac{4}{3}}u$. Our main result is to show that the existence of type II solutions blows up at any k points with arbitrary k blow-up rates. The inner-outer gluing method has been employed.

On the Blow-Up of Solutions of a Weakly Dissipative Modified Two-Component Periodic Camassa-Holm System

open access: yesJournal of Applied Mathematics, 2012
We study the Cauchy problem of a weakly dissipative modified two-component periodic Camassa-Holm equation. We first establish the local well-posedness result.

Blow up profiles for a quasilinear reaction-diffusion equation with weighted reaction

open access: yes, 2019
We perform a thorough study of the blow up profiles associated to the following second order reaction-diffusion equation with non-homogeneous reaction: $$ \partial_tu=\partial_{xx}(u^m) + |x|^{\sigma}u^p, $$ in the range of exponents $10$.

Wave Breaking and Global Existence for the Generalized Periodic Camassa-Holm Equation with the Weak Dissipation

open access: yesAdvances in Mathematical Physics, 2022
In this paper, a family of the weakly dissipative periodic Camassa-Holm type equation cubic and quartic nonlinearities is considered. The precise blow-up scenarios of strong solutions and several conditions on the initial data to guarantee blow-up of the

Non-self-similar blow-up in the heat flow for harmonic maps in higher dimensions

open access: yes, 2014
We analyze the finite-time blow-up of solutions of the heat flow for $k$-corotational maps $\mathbb R^d\to S^d$. For each dimension $d>2+k(2+2\sqrt{2})$ we construct a countable family of blow-up solutions via a method of matched asymptotics by glueing a

Blow-up solutions for a Blow-up solutions for a Blow-up solutions for a $p$-Laplacian elliptic equation of logistic type with singular nonlinearity

open access: yes, 2015
In this paper, we deal with existence, uniqueness and exact rate of boundary behavior of blow-up solutions for a class of logistic type quasilinear problem in a smooth bounded domain involving the $p$-Laplacian operator, where the nonlinearity can have a singular behavior.

The blow-up solutions of integral equations [PDF]

open access: yesColloquium Mathematicum, 1999
A class of nonlinear Volterra equations of the form \[ u(t)=\int_{0}^{t}k(t-\tau)r(s)g(u(s)+h(s)) ds, \quad t>0 \] is considered. These equations are motivated by models of processes in diffusive media which have an explosive character.

The Blow-up Rate of Solutions to Boundary Blow-up Problems for the Complex Monge–Ampère Operator [PDF]

open access: yesmanuscripta mathematica, 2006
Let \(D\subset \mathbb C^n\) be a bounded strongly pseudoconvex domain with smooth boundary. Solutions to the complex Monge-Ampère equations of type \((dd^c u)^n (z) = \exp(K u(z))\), \(K>0\), which explode at every boundary point of \(D\) generate Kähler-Einstein metrics and are therefore well studied [\textit{S.-Y. Cheng, S.-T. Yau}, Commun.
