Solutions for some non-linear fractional differential equations with boundary value problems

In recent years, X.J.Xu [1] has been proved some results on mixed monotone operators.  Following the paper of X.J.Xu, we study the existence and uniqueness of the positive solutions for non-linear differential equations with boundary value problems.

A posteriori error estimates for non-linear parabolic equations

We consider space-time discretizations of non-linear parabolic equations. The temporal discretizations in particular cover the implicit Euler scheme and the mid-point rule. For linear equations they correspond to the well-known A-stable θ-schemes. The spatial discretizations consist of standard conforming finite element spaces that can vary from one time-level to the other. The spatial meshes m...

Universal estimates for parabolic equations and applications for non-linear and non-local problems

We obtain some ”universal” estimates for L2-norm of the solution of a parabolic equation via a weighted version of H-norm of the free term. More precisely, we found the limit upper estimate that can be achieved by transformation of the equation by adding a constant to the zero order coefficient. The inverse matrix of the higher order coefficients of the parabolic equation is included into the w...

Non-uniqueness for Non-negative Solutions of Parabolic Stochastic Partial Differential Equations

Pathwise non-uniqueness is established for non-negative solutions of the parabolic stochastic pde ∂X ∂t = ∆ 2 X +XẆ + ψ, X0 ≡ 0 where Ẇ is a white noise, ψ ≥ 0 is smooth, compactly supported and non-trivial, and 0 < p < 1/2. We further show that any solution spends positive time at the 0 function.

Geometric Solutions to Non-linear Differential Equations

A general formalism to solve nonlinear differential equations is given. Solutions are found and reduced to those of second order nonlinear differential equations in one variable. The approach is uniformized in the geometry and solves generic nonlin-ear systems. Further properties characterized by the topology and geometry of the associated manifolds may define global properties of the solutions.
