I read "Ordinal Differential Equations" by V.I. Arnold (in russian). In 1st lesson he told about differential 1-forms and explained form's ingration. Also he told about monodromy. In the next lesson he told about attractors:)
Can you suggest me "book for mathematician", please? It means that in the book I can read not only about solving and DE -- I can read about principles, about ideas and theories.
(I want to understand what is holonomy. Thats why I find good book about ODE.)
Thanks.
