The nonlinear theory of oscillating systems brings new aspects into the study of variable stars. Beyond the comparison of linear periods and the estimate of stability, the appearance and disappearance of possible modes can be studied in detail. While nonlinearity in stellar pulsations is not a complicated concept, it generally requires extensive and sophisticated numerical studies. Therefore, the development of appropriate computational tools is required for applications of nonlinear theory to real phenomena in variable stars an overview is given of the new frontiers of variable star studies and further development is encouraged. Covered are fundamental theory, interesting observational facts, and the numerical modeling. For individual titles, see A95-74816 through A95-74877.
