Introduction to the theory of exterior forms

This book is a brief introduction to the theory of external forms. It consists of three chapters, which are considered: 1) algebra of external forms, 2) external differentiation, 3) integration of forms according to chains. The author is limited to the consideration of external forms and chains in the final Euclidean space. But this material gives a sufficient idea of ​​the relationship between the conjugation between the spaces of forms and chains and the main pairs of conjugated operators. The book is written very simple and understandable. Lays and reasoning are everywhere carried out without significant gaps.
The book can be useful to students of mathematical specialties of universities who listen to analysis and geometry courses. It is also possible that it will be used by mechanics and physicists who are interested in the methods of tensor calculus
