DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GDEq/136/">E
 quivalence of scalar ODEs under contact\, point and fiber-preserving trans
 formations</a>\nby Boris Doubrov as part of Geometry of differential equat
 ions seminar\n\n\nAbstract\nIt is known that the equivalence problem for s
 calar ODEs of order 3 and higher can be solved via the construction of a c
 anonical Cartan connection. The invariants then appear as part of the curv
 ature of this connection. This allows to describe explicitly all scalar OD
 Es of order 3 and higher that can be brought to the trivial equation by co
 ntact transformations. The goal of this talk is to show how most of this s
 tory can be extended to the equivalence of scalar ODEs under point and fib
 er-preserving transformations.\n
