Le Matematiche, 2010 In this paper we give a survey of some recent results obtained via symmetrization methods for solutions of elliptic equations in the form A(u) = H(x, u, Du), where the principal term is a laplacian-type operator and H(x, u, Du) grows with respect to Du ...

Linear and Nonlinear Perturbed Wave Equations
, 2008 We consider several Cauchy problems for the wave equation with some perturbation. First of all, we consider the wave equation with a metric perturbation, that is, we consider the d'Alembert operator in the Schwarzschild metric (which is a model for a ...

Strongly interacting blow up bubbles for the mass critical NLS
, 2018 International audienceWe construct a new class of multi-solitary wave solutions for the mass critical two dimensional nonlinear Schrodinger equation (NLS). Given any integer K>1, there exists a global (for positive time) solution of (NLS) that decomposes

Numerical approximations for blow-up problems [PDF]
, 2003 Estudiamos el comportamiento asintótico de aproximaciones numéricas para problemas con blow-up. Probamos que al aproximar este tipo de problemas muchas veces los métodos usuales reproducen el comportamiento asintótico de la solución continua, sin embargo

On the blow-up rate for fast blow-up solutions arising in an anisotropic crystalline motion
, 2003 We consider the asymptotic behavior of motion of polygonal convex curves by crystalline curvature in the plane. There appear spontaneously two types of singularity: one is single point extinction and the other is degenerate pinching.

The Blow-Up of the Local Energy Solution to the Wave Equation with a Nontrivial Boundary Condition
MathematicsIn this study, we examine the wave equation with a nontrivial boundary condition. The main target of this study is to prove the local-in-time existence and the blow-up in finite time of the energy solution.

Blow-up with logarithmic nonlinearities
, 2007 We study the asymptotic behaviour of nonnegative solutions of the nonlinear diffusion equation in the half-line with a nonlinear boundary condition,{ut=uxx−λ(u+1)logp(u+1),(x,t)∈R+×(0,T),−ux(0,t)=(u+1)logq(u+1)(0,t),t∈(0,T),u(x,0)=u0(x),x∈R+, with p,q,λ ...

Renormalization and blow up for wave maps from $S^2 \times \mathbb{R}$ to $S^2$ [PDF]
We construct a one parameter family of nite time blow ups to the co-rotational wave maps problem from $S^2\times R$ to $S^2$ parameterized by $\nu \epsilon (\frac{1}{2},1]$.

Blow up of solutions to ordinary differential equations arising in nonlinear dispersive problems
Electronic Journal of Differential Equations, 2018 We study a new class of ordinary differential equations with blow up solutions. Necessary and sufficient conditions for finite blow up time are proved.
