The Stavanger Algebraic Geometry Seminar
Autumn 2015: The seminar takes place on Wednesdays 10:15-12:00 (at most). When
nothing else (guests) is on, we will be reading about toric varieties,
following the books of Fulton and Cox-Little-Schenck.

Compactified universal Jacobian and the double ramification cycle
On the moduli space of projective smooth n-marked genus g curves, the double
ramification cycle is the codimension g cycle corresponding to curves admitting
a principal divisor of a given form. The Eliashberg problem is about finding a
geometrical meaningful extension of the double ramification cycle to the moduli
space of stable curves, together with an explicit expression of it in terms of
tautological cycles. After going through known results and approaches to the
Eliashberg problem, we will show how to use the compactified universal Jacobian
in the sense of Melo to build up a strategy extending known results up so far.
