Title         : On the Dynamics of Predator-Prey Systems with Beddngton
DeAngelis type Functional Responses

Abstract  : We consider two dimensional predator-prey systems with
Beddington DeAngelis type functional response.  Here, the necessary and
suﬃcient conditions of the considered systems when it has at least one
w-periodic solution is found. This study is mainly based on continuation
theorem in coincidence degree theory. By using the study of  Cui and
Takeuchi, to obtain the globally attractive w-periodic solution of the
given systems, an equality is given as the necessary and suﬃcient condition.
Additionally, for the system with Beddington DeAngelis type functional
response, the open problem that was given in the discussion part of the
study of Fan and Kuang is solved.
