報告題目:Some nonlinear problems with lack of compactness: new results and open questions
報告地點: 應用數學研究中心報告廳(計算機樓718#)
歡迎廣大師生參加!
摘要:
The first part of the talk deals with the existence of nontrivial entire solutions for critical Hardy quasilinear systems driven by general (p,q) elliptic operators of Marcellini types. Existence is derived as an application of the mountain pass geometry and the concentration-compactness principle of Lions. The constructed solution has both components nontrivial, that is it solves the actual system, which does not reduce into an equation. In the second part we present new results on existence of solutions for degenerate Kirchhoff problems, involving (p,q)-fractional operators as well as critical nonlinearities. The results improve or complement previous theorems for the quasilinear (p,q) scalar as well as vectorial problems. The conclusions also raise, and leave open, a number of other intriguing questions, which are briefly presented.
