摘要
证明了广义BBM-Burgers方程的Cauchy问题vt-αvxxt-βvxx+γvxxxx+f(v)x=G(v)+h(vx)x+g(v)xx,x∈R,t>0,v(x,0)=v0(x),x∈R存在唯一整体强解v∈C([0,∞);Hs(R))∩C1([0,∞);Hs-2(R))(s≥4)和唯一的整体古典解,并给出解的衰减估计.
The existence and uniqueness of the global generalized solution v∈C([0,∞);Hs(R))∩C1([0,∞);Hs-2(R))(s≥4)and the global classical solution of a generalized BBM-Burgers equationvt-αvxxt-βvxx+γvxxxx+f(v)x=G(v)+h(vx)x+g(v)xx,x∈R,t〉0,v(x,0)=v0(x),x∈Rwere proved. Moreover, the decay estimate of the solution was given.
