The Lax representation of the CHESCS is presented. The conservation laws for CHESCS are constructed. The peakon solution, N-soliton, N-cuspon, N-positon, and N-negaton solutions of CHESCS are obtained by using Darboux transformation and the method of variation of constants.展开更多

In all kinds of market transactions, there are more or less inIbrmation asynunetry phenomena. Asynmaetric information makes supply chain unable to give a real reaction to the relationship between market supply and demand, and the personnel in the channels of supply chain are unable to make the optimal pricing, so that the overall profits are affected. Therefore, asymmetric information should be controlled within the normal range, for the purpose of ensuring the normal operation and healthy development of the market transactions.展开更多
