Roughly speaking, valuations and derivations are measures of contact, derivations are
algebraic differential equations and after Kaplansty’s theorem valuations may be considered as
generalized arcs. Then there are two problems:
- Relation between valuation and derivation corresponding to "generalized arc solution of a differential equation"
- Structure of the space of arcs solution of a differential equation.
In our talk we will explain the history and the actuality of both problems
