Description : Abstract : We give some basic concepts on group actions and theorems in invariant theory useful for the contrcution and the study of Landau polynomials. We apply them to the study of the isotropy groups of extrema of Landau polynomials. We explain some technique for finding new extrema from old ones and we state some recent results concerning Landau theory of second order phase transitions.
