Jian-Wen Peng, Xinmin Yang · International Journal of Mathematics and Mathematical Sciences · 2005
We introduce a new model of the system of generalized vector quasi‐equilibrium problems with upper semicontinuous set‐valued maps and present several existence results of a solution for this system of generalized vector quasi‐equilibrium problems and its special cases. The results in this paper extend and improve some results in the literature.
