报告摘要
Multidimensional solitons are objects which have been studied in detail, chiefly theoretically, but in some settings experimentally too, in nonlinear optics and Bose-Einstein condensates (BECs), in the course of past twenty years. The most important problem in that context is the stability of multidimensional solitons and solitary vortices. Recently, novel perspectives for the studies in this field have been brought to the attention of  researchers. These developments reveal new theoretical and experimental settings that can support stable two- and three-dimensional (2D and 3D) solitons and vortices in optics and BEC. The present talk aims to  provide an overview of some well-established results and ongoing developments in this field. In particular,  as concerns matter-wave solitons, it has recently been predicted that a new mechanism, based on spin-orbit coupling, can stabilize two-component solitons of a semi-vortex type in the 2D and 3D space (in 2D they represent the ground state, while in 3D they are metastable objects).
