Abstract
We study the following time fractional complex nonlinear Ginzburg-Landau equation:{eâiÏ0CDtαuââ³u=eiγ|u|pâ1u,xâRN,t>0,u(0,x)=u0(x),xâRN, where 0<α<1, γâR, âÏ+Ïα2<Ï<ÏâÏα2, p>1, u0âLq(RN) (qâ¥qc=N(pâ1)2 and qâ¥1) is a complex-valued function, and Dtα0Cu=âât0It1âα(u(t,x)âu(0,x)), where It1âα0 denotes a left Riemann-Liouville fractional integral of order 1âα. By defining two operators and establishing some estimates of them, we prove the well-posedness of the mild solution for this problem in C([0,T],Lq(RN)) and L2rqαN(râq)((0,T),Lr(RN)), where r satisfies 1/qâ1/r<2/N. Moreover, we also obtain the existence of global solutions when âu0âLqc(RN) is sufficiently small.
