摘要:
We classify the volume preserving stable hypersurfaces in the real projective space RPn. As a consequence, the solutions of the isoperimetric problem are tubular neighborhoods of projective subspaces RPk subset of RPn (starting with points). This confirms a conjecture of Burago and Zalgaller from 1988 and extends to higher dimensions previous result of M. Ritore and A. Ros on RP3. We also derive an Willmore type inequality for antipodal invariant hypersurfaces in S-n.
