In this paper we study the global approximate multiplicative controllability for nonlinear degenerate parabolic Cauchy problems. In particular, we consider a one-dimensional semilinear degenerate reaction-diffusion equation in divergence form governed ...

A new method for large time behavior of degenerate viscous Hamilton--Jacobi equations with convex Hamiltonians [PDF]
We investigate large-time asymptotics for viscous Hamilton--Jacobi equations with possibly degenerate diffusion terms. We establish new results on the convergence, which are the first general ones concerning equations which are neither uniformly ...

Embedding Operators in Vector-Valued Weighted Besov Spaces and Applications
The embedding theorems in weighted Besov-Lions type spaces ๐ต๐,๐ ๐,๐,๐พ (ฮฉ;๐ธ0,๐ธ) in which ๐ธ0,๐ธ are two Banach spaces and ๐ธ0โ๐ธ are studied. The most regular class of interpolation space ๐ธ๐ผ between ๐ธ0 and E is found such that the mixed differential operator ...

On the Weak Characteristic Function Method for a Degenerate Parabolic Equation
For a nonlinear degenerate parabolic equation, how to impose a suitable boundary value condition to ensure the well-posedness of weak solutions is a very important problem.

Degenerate singular parabolic problems with natural growth [PDF]
In this paper, we study the existence and regularity results for nonlinear singular parabolic problems with a natural growth gradient term \[\begin{cases}\frac{\partial u}{\partial t}-\operatorname{div}((a(x,t)+u^{q})|\nabla u|^{p-2}\nabla u)+d(x,t)\frac{

Local Calderรณn-Zygmund estimates for parabolic equations in weighted Lebesgue spaces
We prove local Calderรณn-Zygmund type estimates for the gradient of weak solutions to degenerate or singular parabolic equations of $ p $-Laplacian type with $ p > \frac{2n}{n+2} $ in weighted Lebesgue spaces $ L^q_w $.

Second order mean field games with degenerate diffusion and local coupling [PDF]
We analyze a (possibly degenerate) second order mean field games system of partial differential equations. The distinguishing features of the model considered are (1) that it is not uniformly parabolic, including the first order case as a possibility ...

Expansion of positivity to a class of doubly nonlinear parabolic equations
We establish the expansion of positivity of the nonnegative, local, weak solutions to the class of doubly nonlinear parabolic equations $$\partial_t (u^{q}) -\operatorname{div}{(|D u|^{p-2} D u)}=0, \qquad\ p>1 \ \text{and} \ q>0$$ considering ...

Liouville properties and critical value of fully nonlinear elliptic operators [PDF]
We prove some Liouville properties for sub- and supersolutions of fully nonlinear degenerate elliptic equations in the whole space. Our assumptions allow the coefficients of the first order terms to be large at infinity, provided they have an appropriate

Stability for degenerate parabolic equations [PDF]
The authors study the stability of the solutions of the evolutionary \(p\)-Laplace equation \[ {\partial u\over\partial t}= \nabla\cdot(|\nabla u|^{p-2}\nabla u) \] under variations of the parameter \(p\). The problem is delicate, since the underlying Sobolev space varieties with \(p\). The boundary values are given on the parabolic boundary of a space-
