The Kuhn-Tucker type necessary conditions of weak efficiency are given for the problem of mini-mizing a vector function whose each component is the sum of a dif
By constructing a special cone and using cone compression and expansion fixed point theorem,this paper presents some existence results of positive solutions of
Suppose that there are two nonparametric populations x and y with missing data on both of them.We are interested in constructing confidence intervals on the qua
We describe and analyze a simple SIS model with treatment.In particular,we give a completely qualitative analysis by means of the theory of asymptotically auton
Non-linear numerical method is applied to solve the viscons-elastic-plastic material impact problem.The finite element simulation agrees with the celebrated Eur
In this paper,a nonlinear predator reproduction and prey competition model with diffusion is discussed.Some existence and non-existence results concing non-cons
A proper k-edge coloring of a graph G is called adjacent vertex distinguishing acyclic edge coloring if there is no 2-colored cycle in G and the color set of ed
