SOME EXISTENCE THEOREMS OF COMMON AND COINCIDENCE SOLUTIONS FOR A CLASS OF SYSTEMS OF FUNCTIONAL EQUATIONS ARISING IN DYNAMIC PROGRAMMING

摘要

Some existence theorems of common and coincidence solutions for a class of moregeneral systems of functional equations arising in dynamic programming are shown.Theresults presented in this paper not only contain the corresponding results of[6,7]as specialcases,but also give an existence theorem of solutions for a class of functional equationssuggested by Wang recently.
