Least-squares function-valued Padé-type approximation and its application in solving integral equations

To solve the Fredholm integral equations of the second kind,a new notion of the least-squares orthogonal polyno-mials of function-valued Padé-type approximation is introduced.On the basis of the error formula,the least-squares function-valued Padé-type approximation is constructed.Their existence and uniqueness are studied.A recursive computation formula of the least-squares function-valued Padé-type approximation is given.In the end,an example is given to show that the method is effiective and stable.     

Interior-point algorithm based on general kernel function for monotone linear complementarity problem

A polynomial interior-point algorithm is presented for monotone linear complementarity problem (MLCP) based on:a class of kernel functions with the general barrier term, which are called general kernel functions. Under the mild conditions for the barrier term, the complexity bound of algorithm in terms of such kernel function and its derivatives is obtained. The approach is actually an extension of the existing work which only used the specific kernel functions for the MLCP.
