摘要Blowup ring profiles have been investigated by finding non-vortex blowup solutions of nonlinear Schrodinger equations (NLSEs) (cf Fibich et al (2005) [7] and Fibich et al. (2007) [8]) However, those solutions have infinite L-2 norm, so one may not maintain the ring profile all the way up to the singularity To find H-1 non-vortex blowup solutions with ring profiles, we study the blowup solutions of two-component systems of NLSEs with nonlinear coefficients beta and nu(j), J = 1. 2 When beta < 0 and nu(1) >> nu(2) > 0, the two-component system can be transformed into a multi-scale system with fast and slow variables which may produce H-1 blowup solutions with non-vortex ring profiles. We use the localized energy method with symmetry reduction to construct these solutions rigorously On the other hand, these solutions may describe steady non-vortex bright ring solitons Various types of ring profiles including m-ring and ring-ring profiles are presented by numerical solutions (C) 2010 Elsevier B.V.
