Soliton solutions of a class of generalized nonlinear evolution equations are discussed ana-lytically and numerically. This is done by using a travelling wave m
Abstract. In this paper, we introduce a new approach to characterize the isomor-phisms of circulant digraphs. In terms of this method, we completely determine t
In this paper,the necessary and sutlicient conditions for general one-step methoos to be exponentially fitted at q0∈C are given, A class of multtderivative hyb
Let {X, Xi;i≥1} be a sequence of i.i.d.r.v'.s, Z(t) =∑ti=1 Xi, t≥O.Consider the renewal process N(t) = inf{x; Z(x) > t}. In this paper we study the neces
