摘要
In this paper, the constrained dispersionless BKP hierarchy are given by restricting the formal Laurent series L of the dispersionless BKP hierarchy to L = k + mu(t)/k-rho(t) + mu(t)/k-rho(t). Its additional symmetries are given by introducing vital formal Laurent series Y2n+1. The additional flows form the nonabelian Z-grading Lie algebra. Furthermore, the additional flows acting on mu(t) and rho(t) are presented.
