文摘In this paper,extended projective Riccati equation method is presented for constructing more new exactsolutions of nonlinear differential equations in mathematical physics,which is direct and more powerful than projectiveRiceati equation method,In order to illustrate the effect of the method,Broer-Kaup-Kupershmidt system is employedand Jacobi doubly periodic solutions are obtained.This algorithm can also be applied to other nonlinear differentialequations.
