摘要:

In this paper, the existence and the uniqueness of the local generalized solution and the local classical solution of the Cauchy problem for the generalized BBM-Burgers equation
vt − αΔvt − βΔvγΔ2v +∑nj=1fj (v)xj = Δg(v) + G(v), x ∈ Rn, t > 0 (1)
are proved. The existence and the uniqueness of the global generalized solution and the global classical solution for the Cauchy problem of equation (1) are proved when n = 3, 2, 1. Moreover, the decay property of the solution is discussed.
