In this paper we study the existence of positive almost periodic solutions for a class of almost periodic LotkaαVolterra type systems with delays. Applying Schauder's fixed point theorem we obtain a general criterion of the existence of positive almost periodic solutions. This criterion can be used

## Abstract The paper deals with the existence, multiplicity and nonexistence of positive radial solutions for the elliptic system div(|β|^__p__ β2^β) + __Ξ»k~i~__ (|__x__ |) __f^i^__ (__u__~1~, β¦,__u~n~__) = 0, __p__ > 1, __R__~1~ < |__x__ | < __R__~2~, __u~i~__ (__x__) = 0, on |__x__ | = __R__~1~
## Abstract In this paper, we establish several criteria for the existence, multiplicity, nonexistence of positive periodic solutions of the following system by combining some new properties of Green's function together with Krasnosel'skΔ fixed point theorem on the compression and expression of co
## Abstract In this paper, we study the mathematical model of electron beam focusing system where __a__>0,__b__β©Ύ0 are constants, find conditions for the existence of positive Οβperiodic solution of the above equation by using analytical method and comparison theory, and prove the existence of pos
On the existence of periodic solutions for the quasi-linear third order system of O.D.Es In this paper we concern with the nonlinear third order quasi-linear system of ordinary differential equations as: where X β IR n and Ξ is a diagonal matrix. We obtain some simple sufficient conditions for the
