Homology of saddle point reduction and applications to resonant elliptic systems
Li, Chong; Liu, Shibo; 刘轼波 (PERGAMON-ELSEVIER SCIENCE LTD, 2013)In the setting of saddle point reduction, we prove that the critical groups of the original functional and the reduced functional are isomorphic. As application, we obtain two nontrivial solutions for elliptic gradient ...
