Outline of Final Research Achievements

We study elliptic partial differential equations in symmetric domains. Let H and G be closed subgroups of the orthogonal group such that H is a closed subgroup of G and the domain is G invariant. Then we show the existence of a positive solution which is H invariant but G non-invariant under suitable assumptions of H, G and the coefficient function of the equation. Such a solution is obtained as a least energy solution. Here a least energy solution is a solution which is a minimizer of the Rayleigh quotient. Our theorem ensures the existence of various solutions which has a weak symmetry but does not have a strong symmetry.
