| Abstract: | Recent advances in the study of parametrically excited hydrodynamical solitons are described.These include soliton-soliton interactions,the ordering rules of polarity in the formation of stable multisoliton chains,and the spatiotemporal oscillations of the chains.The experimentally observed phenomena are well reproduced by numerical simulations using the parametrically driven,damped nonlinear Schrdinger equation. |

| Keywords: | parametric resonance polarity solitons spatio-temporal oscillations of solitons |
