A note on an Counter Example of Dacorogna
Yan Tang, Shiqing Zhang
In this short note,we correct a well-known counter example of the famous book of Dacorogna[2].
Generalized Mountain Pass Lemma Related with a Closed Subset and Locally Lipschitz Functionals
Fengying Li, Bingyu Li, Shiqing Zhang
The classical Mountain Pass Lemma of Ambrosetti-Rabinowitz has been studied, extended and modified in several directions, notable examples would certainly include the generalizatio…
Some Applications of Generalized Mountain Pass Lemma
Fengying Li, Bingyu Li, Shiqing Zhang
The Ghoussoub-Preiss's generalized Mountain Pass Lemma with Cerami-Palais-Smale type condition is a generalization of classical MPL of Ambrosetti-Rabinowitz, we apply it to study t…
New Periodic Solutions for Second Order Hamiltonian Systems with Local Lipschitz Potentials
Li Bingyu, Li Fengying, Zhang Shiqing
Firstly,we generalize the classical Palais-Smale-Cerami condition for functional to the local Lipschitz case,then generalize the famous Benci-Rabinowitz's and Rabinowitz's Sa…
New Quantitative Deformation Lemma and New Mountain Pass Theorem
Liang Ding, Fode Zhang, Shiqing Zhang
In this paper, we obtain a new quantitative deformation Lemma so that we can obtain more critical points, especially for supinf critical value , is a new criti…
