Existence of Almost Periodic Solutions For a Class of Nonlinear Duffing Equations
Duffing equations nonlinear almost periodic Stepanov almost periodic exponential dichotomy
2009/6/16
In this paper, we discuss the existence of almost periodic solutions for a class of nonlinear
Duffing equations. Some new theorems are established to ensure that the existence
of almost periodic sol...
EXISTENCE OF RADIAL SOLUTIONS FOR A FOURTH ORDER PARABOLIC EQUATION
Fourth order parabolic equation Radial solution Existence
2008/11/26
We consider an initial-boundary problem for a fourth order nonlinear parabolic equation.
The problem as a model arises in epitaxial growth of nanoscale thin films. Relying
on some necessary uniform ...
THE EXISTENCE AND NONEXISTENCE OF POSITIVE PERIODIC SOLUTIONS FOR NEUTRAL DELAY COMPETITION MODEL
Coincidence degree neutral functional differential equation positive periodic solution
2008/11/25
By using the theory of coincidence degree, sufficient conditions for the existence and
nonexistence of positive periodic solutions of a class of neutral delay competition model
are obtained.
Existence of Limit Cycles in a Predator-Prey System With a Functional Response of the Form Arctan(ax)
Predator prey system limit cycle unctional response
2008/11/25
We consider a predator prey system with the functional response of the form
µ(x) = arctan(ax); a > 0. The main concern in this paper is the existence of
limit cycles for such system. A necessa...
