In this context, the article first introduced the importance of the development of e-commerce SMEs, and then based on the actual operation of the community put forward and analyzed the current e-commerce development under the existing problems, and finally based on the actual lack of effective Development Strategy of E - commerce for Small and Medium - sized Enterprises.展开更多

The explicit construction of the Jack polynomials is an essential ingredient in solving the Calogero–Sutherland model, which is a one-dimensional integrable system. Starting from a special class of the Jack polynomials associated to the hook Young diagram, we find a systematic way in the explicit construction of the transition coefficients in the power-sum basis, which is closely related to a set of mutually commuting operators, i.e. the conserved charges.展开更多
