Extensions of functions from subspaces of metric spaces
Hevessy, Michal ; Hušek, Miroslav (advisor) ; Vejnar, Benjamin (referee)
Function extension is a classical problem in mathematics. In this thesis we look into an extesion of realvalued functions defined on metric spaces. The first chapter is intro- ductory and describes extension problem. In the second one we discuss a known method for extension of special family of uniformly continuous functions and show that the me- thod can be modified for continuous functions. The third chapter examines a method for extension of continuous functions described by Whitney. Finally, in the last chapter we show a characterisation of uniformly continuous function, having uniformly continuous extensions. 1
