Title: Equivalence of scalar ODEs under contact, point and
       fiber-preserving transformations
Language: English

Zoom Passcode: 1405

Abstract:

It is known that the equivalence problem for scalar ODEs of order 3 and
higher can be solved via the construction of a canonical Cartan
connection. The invariants then appear as part of the curvature of this
connection. This allows to describe explicitly all scalar ODEs of order
3 and higher that can be brought to the trivial equation by contact
transformations. The goal of this talk is to show how most of this story
can be extended to the equivalence of scalar ODEs under point and
fiber-preserving transformations.


The seminar meets on Wednesday evenings at 19:20 MSK in Zoom,
