Title: On equivalence of planar webs

Abstract:
In this talk, I'll discuss the equivalence problem for planar d-webs.

To this end, the fields of rational differential invariants will be found, and natural geometric objects related to planar webs will be discussed.

The cases of d-webs with d<6 will be discussed in detail.

Please download the formula file pl.pdf and keep it handy during the talk so that the speaker can refer to it.
