A Generalized Mountain Pass Lemma with a Closed Subset for Locally Lipschitz Functionals
Fengying Li, Bingying 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…
Solutions for fourth-order Kirchhoff type elliptic equations involving concave-convex nonlinearities in
Dong-Lun Wu, Fengying Li
In this paper, we show the existence and multiplicity of solutions for the following fourth-order Kirchhoff type elliptic equations \begin{eqnarray*} Δ^{2}u-M(\|\nabla u\|_{2}^{2})…
Large Essential norm of Toeplitz operators and Hankel operators on the weighted Bergman space
Fengying Li
In this paper, we show that on the weighted Bergman space of the unit disk the essential norm of a noncompact Hankel operator equals its distance to the set of compact Hankel opera…
Nonplanar Periodic Solutions for Spatial Restricted N+1-Body Problems
Fengying Li, Shiqing Zhang, Xiaoxiao Zhao
We use variational minimizing methods to study spatial restricted N+1-body problems with a zero mass moving on the vertical axis of the moving plane for N equal masses. We prove th…
