Quasi-equilibrium problems and fixed point theorems of l.s.c mappings
Speaker: Nguyen Xuan Tan

Time: 9h00, Wednesday, January 13, 2016
Location: Room 4, Building A14, Institute of Mathematics, 18 Hoang Quoc Viet, Cau Giay, Hanoi
Abstract: In this talk, we apply our new results on quasi-variational inequality problems  to generalized quasi-equilibrium problems. Some sufficient conditions on the existence of solutions are shown. In particular, we establish several results on the existence of solutions to fixed points  of lower semi-continuous mappings without conditions on closedness of values.
These generalize some well-known fixed point theorems obtained by previous authors as F. E. Browder and Ky Fan,  X. Wu, L. J. Lin, and Z. T. Yu etc.
