Introduction to d–spaces theory

Krzysztof Drachal

The aim of this paper is to present the basics of differential spaces theory. In particular differential spaces in a sense of Sikorski are exposed. They are some generalisation of a smooth manifold concept. Except a concise and general exposition to the topic at the introductory level, also some new ideas of gluing two spaces are sketched.
