Infinitely Many Elliptic Solutions to a Simple Equation and Applications
Based on auxiliary equation method and Bäcklund transformations, we present an idea to find infinitely many Weierstrass and Jacobi elliptic function solutions to some nonlinear problems.

In this paper, we prove existence of distributional solutions of a nonlinear elliptic system, related to the Keller-Segel model. Our starting point is the boundedness theorem (for solutions of elliptic equations) proved by Guido Stampacchia and Neil ...

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

Some nonlinear elliptic equations from geometry [PDF]
We describe some recent work on certain nonlinear elliptic equations from geometry. These include the problem of prescribing scalar curvature on 𝕊 n , the Yamabe problem on manifolds with boundary, and the best Sobolev inequality on Riemannian manifolds.

F-Expansion Method and New Exact Solutions of the Schrödinger-KdV Equation
F-expansion method is proposed to seek exact solutions of nonlinear evolution equations. With the aid of symbolic computation, we choose the Schrödinger-KdV equation with a source to illustrate the validity and advantages of the proposed method. A number
