  This paper is focused on quasi-periodic wave solutions of (3+1) generalized
BKP equation. Because of some difficulties in calculations of N=3 periodic
solutions, hardly ever has there been a study on these solutions by using
Rieamann theta function. In this study, we obtain one and two periodic wave
solutions as well as three periodic wave solutions for (3+1) generalized BKP
equation. Moreover we analyse the asymptotic behavior of the periodic wave
solutions tend to the known soliton solutions under a small amplitude limit.
