چکیده    in this paper, a new fractional sub-equation method is proposed for finding exact solutions of fractional partial differential equations (fpdes) in the sense of modified riemann-liouville derivative. with the aid of symbolic computation, we choose the space-time fractional zakharov-kuznetsov-benjamin-bona-mahony (zkbbm) equation in mathematical physics with a source to illustrate the validity and advantages of the novel method. as a result, some new exact solutions including solitary wave solutions and periodic wave solutions are successfully obtained. the proposed approach can also be applied to other nonlinear fpdes arising in mathematical physics.
