The purpose of this note is to study the three manifold invariants Qp(ML).For lens spaces L(7,1)and (7,2),we compute Q5(L(7,1) and Q5(L(7.2)) concretely,which enables us to prove that the in-variants can distinguish homotopy equivalence manifolds. 相似文献

In this paper we discuss the quasilinear parabolic equationU_■=▽(u~u(1-u)~β.Vu)+■(x,t.u)▽u+C(x,t,u)which is degenerate at u =0 and u=1.Let u(x,t)be a weak solution of the equation satisfying0相似文献
