Stationary solutions to a Keller-Segel chemotaxis system
(IOS PRESS, 2006)
We consider the following stationary Keller-Segel system from chemotaxis
Self-generated interior blow-up solutions in fractional elliptic equation with absorption

New solutions for Trudinger-Moser critical equations in R-2
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
Let Omega be a bounded, smooth domain in R-2. We consider critical points of the Trudinger-Moser type functional J(lambda) (u) = 1/2 integral(Omega)vertical bar del u vertical bar(2) - lambda/2 integral(Omega)e(u2) in ...
Positive solutions for systems of quasilinear equations with non-homogeneous operators and weights
(Walter de Gruyter, 2020)
In this paper we deal with positive radially symmetric solutions for a boundary value problem containing a strongly nonlinear operator. The proof of existence of positive solutions that we give uses the blow-up method as ...
A Particle System with Explosions: Law of Large Numbers for the Density of Particles and the Blow-Up Time
(2012)
Consider a system of independent random walks in the discrete torus with creation-annihilation of particles and possible explosion of the total number of particles in finite time. Rescaling space and rates for diffusion/ ...

Singularity formation for the two-dimensional harmonic map flow into S-2
(Springer, 2020)
We construct finite time blow-up solutions to the 2-dimensional harmonic map flow into the sphere S-2,

Small random perturbations of a dynamical system with blow-up
(Elsevier Inc, 2012-01)
We study small random perturbations by additive white-noise of a spatial discretization of a reaction–diffusion equation with a stable equilibrium and solutions that blow up in finite time. We prove that the perturbed ...
Green's function and infinite-time bubbling in the critical nonlinear heat equation
(European Mathematical Society, 2020)
Let Omega be a smooth bounded domain in R-n, n >= 5. We consider the classical semilinear heat equation at the critical Sobolev exponent.
