Wellposedness of Solutions of a Parabolic-elliptic System

چکیده
We show existence of a unique, regular global solution of the parabolic-elliptic system ut + f(t, x, u)x + g(t, x, u) + Px = (a(t, x)ux)x and −Pxx + P = h(t, x, u, ux) + k(t, x, u) with initial data u|t=0 = u0. Here inf(t,x) a(t, x) > 0. Furthermore, we show that the solution is stable with respect to variation in the initial data u0 and the functions f , g etc. Explicit stability estimates are provided. The regularized generalized Camassa–Holm equation is a special case of the model we discuss.

Exploding solutions for a nonlocal quadratic evolution problem
We consider a nonlinear parabolic equation with fractional diffusion which arises from modelling chemotaxis in bacteria. We prove the wellposedness, continuation criteria and smoothness of local solutions. In the repulsive case we prove global wellposedness in Sobolev spaces. Finally in the attractive case, we prove that for a class of smooth initial data the L∞x -norm of the corresponding solu...

متن کاملExistence of at least three weak solutions for a quasilinear elliptic system
In this paper, applying two theorems of Ricceri and Bonanno, we will establish the existence of three weak solutions for a quasilinear elliptic system. Indeed, we will assign a differentiable nonlinear operator to a differential equation system such that the critical points of this operator are weak solutions of the system. In this paper, applying two theorems of R...
متن کاملExistence and multiplicity of positive solutions for a class of semilinear elliptic system with nonlinear boundary conditions
This study concerns the existence and multiplicity of positive weak solutions for a class of semilinear elliptic systems with nonlinear boundary conditions. Our results is depending on the local minimization method on the Nehari manifold and some variational techniques. Also, by using Mountain Pass Lemma, we establish the existence of at least one solution with positive energy.
متن کاملLarge mass self-similar solutions of the parabolic-parabolic Keller-Segel model of chemotaxis.
In two space dimensions, the parabolic-parabolic Keller-Segel system shares many properties with the parabolic-elliptic Keller-Segel system. In particular, solutions globally exist in both cases as long as their mass is less than a critical threshold M(c). However, this threshold is not as clear in the parabolic-parabolic case as it is in the parabolic-elliptic case, in which solutions with mas...
