The dual algorithm for minimax problems is further studied in this paper. The resulting theoretical analysis shows that the condition number of the correspondin
Abstract. A Riccati equation involving a parameter and symbolic computation are used to uni-formly construct the different forms of travelling wave solutions fo
A set of n points in the plane determines a total Cn^2 distances (some of them may be the same). Let rn be the ratio of the maximum distance to the minimum dist
In this paper,the almost periodic nonautonomous diffusive food chain system of threespecies is discussed. By using the comparison theorem and V-function method,
