From the simple Faraday wave experiment with rectangular tanks of variable length and width, or with insection of partitions, the standing or nonpropagating solitons will manifest a number of interesting nonlinear phenomena. These include parameters governing generation, stability, collision dynamics, reflection symmetry, chaotic behaviors, etc., of one or more solitons. Some of the not well-solved problems of the physics and mathematical formulations will be presented.
