Seminar talk, 25 February 2009

Speaker: Valery Yumaguzhin

Title: Differential invariants of webs on $2$-dimensional manifolds

Absract:

In the talk the algebra of scalar differential invariants of $n$-webs on $2$-dimensional manifold will be constructed. There will be computed invariant differentiations of this algebra, its generators and all differential relations among generators.
