摘要
考虑如下耦合非线性Schr?dinger方程的初边值问题:{iu_t+pΔu=(a_(11)|u|~2+a_(12)|v|~2)u,(t,x)∈[0,∞)×Ωiv_t+qΔv=(a_(21)|u|~2+a_(22)|v|~2)v,(t,x)∈[0,∞)×Ωu(t,x)=0,v(t,x)=0,(t,x)∈[0,∞)×Γu(0,x)=u_0(x),v(0,x)=v_0(x),x∈Ω( S)其中Ω是R^2中具有紧光滑边界Γ的区域。当p <0且q <0时,假定(pa_(11)pa_(12)qa_(21)qa_(22))半正定,或者(pa_(11)pa_(12)qa_(21)qa_(22))负定且(u_0,v_0)适当小,证明了初边值问题(S)解的整体适定性。
We consider the initial-boundary value problem for the following coupled nonlinear Schrodinger equations:{iut+pΔu=(a(11)|u|~2+a(12)|v|~2)u,(t,x)∈[0,∞)×Ωivt+qΔv=(a(21)|u|~2+a(22)|v|~2)v,(t,x)∈[0,∞)×Ωu(t,x)=0,v(t,x)=0,(t,x)∈[0,∞)×Γu(0,x)=u0(x),v(0,x)=v0(x),x∈Ω( S)Here,Ω is a domain in R^2 with compact smooth boundary Γ. For p 0 and q 0,we show the global wellposedness of the initial-boundary value problem( S) provided that( pa(11) pa(12) qa(21) qa(22))is positive semi-definite or(pa(11) pa(12) qa(21) qa(22))is negative definite with( u0,v0) suitably small.
