Abstract:

This report is an attempt to answer the following question. Where
exactly does a differential equation contain information about its
variational nature? Apparently, in the general case, the concept of a
presymplectic structure as a closed variational 2-form may not be
sufficient to describe variational principles in terms of intrinsic
geometry. I will introduce the concept of an internal Lagrangian and
relate it to the Vinogradov C-spectral sequence.


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