Symmetry of large solutions of nonlinear elliptic equations in a ball

A compact G-space is called a G-boundary in the sense of Furstenberg ([F1, F2]) if X is minimal and strongly proximal, or equivalently if X is the unique minimal G-invariant

Repeat the exer- cise in homology, for cor G×K H×K and tr G×K H×K (in homology, the hypothesis that G be finite can be supressed, but of course we need [G : H ] < ∞ for the

The bouquet bch(E , A ) will be called the bouquet of Chern characters of the bundle E with connection A (in fact, we will have to modify the notion of G-equivariant vector bundle
