ON THE EXISTENCE AND UNIQUENESS OF PERIODIC SOLUTIONS OF VOLTERRA INTEGRAL DIFFERENTIAL EQUATIONS
Periodic solutions Volterra integro-dif
2007/12/10
摘要 In this paper, we use the contraction principle and the Leray-Schauder principle to deal with the existence of periodic solutions of the Volterra integral differential equation. Some new existence ...
Periodic Solutions and Global Asymptotic Stability of a Delayed Discrete Predator-Prey System with Holling II Type Functional Response
Coincidence degree discrete predator-prey system global asymptotic stability positive periodic solutions
2007/8/7
In this paper, we study the existence and global asymptotic stability of positive periodic solutions of a delayed periodic predator-prey system with Holling II type functional response. By use of the ...
Consider the general competitive system \dot{u}=uM_1(t;u,v), \dot{v}=vM_2(t;u,v), where \partial M_1/\partial v <0, \partial M_2/\partial u <0, M_i(t+T; u,v) = M_i(t; u, v), i =1, 2. under soniccondit...
In this paper, the Josephson equation and its autonomous case are considered. It is shown that for |α|1 or β<γ<-1, there is no periodic solution of the autonomous Josephson equation, For the nonautono...
A REMARK ON PERIODIC SOLUTIONS OF SINGULAR HAMILTONIAN SYSTEMS WITH SUBLINEAR TERMS
Singular Hamiltonian system sublinear pe
2007/8/7
In this paper, we prove the existence of multiple periodic solutions for a class of singular Hamiltonian systems with sublinear terms via variational methods.
PERIODIC SOLUTIONS AND PERIOD-SIMILARITY OF A GROWTH MODEL WITH AGE-STRUCTURED POPULATION
Age-structured population periodic solut
2007/8/7
The present paper deals with the periodic behaviours of an age-structured population model. The period-similarity is proposed, which reveals a certain similar structure between those population models...
