A nonlinear version of Krein Rutman Theorem is established. This paper presents a unified proof of the Krein Rutman Theorem for linear operators and for nonline
This article summarizes our recent work on uniform error estimates for various finite element methods for time-dependent advection-diffusion equations.
Let T_(2k+1) be the set of trees on 2k+1 vertices with nearly perfect matchings, and let S_(2k+2) be the set of trees on 2k+2 vertices with perfect matchings. T
Hausdorff distance between two compact sets, defined as the maximum distance from a point of one set to another set, has many application in computer science. I
This paper discusses the harmonic problems in control systems from two aspects: One is the harmonic control among different subsystems, and the other is the har
Control invariant sets play a key role in model predictive control. Using Lyapunov function,a technique is proposed to design control invariant sets of planar s
In this paper, the authors study the existence and non-existence of positive solutions for singular p-Laplacian equation -△pu = f(x)u~(-α) +λg(x)u~β in R~N,
