Any smooth plane quartic can be reconstructed from its bitangents

** Abstract: **
Any smooth plane quartic can be reconstructed from its bitangents.
It is known since ancient times (the 1860's) that any smooth plane
quartic has exactly 28 bitangents. A long standing question from that era
is: "given only the set of 28 bitangents to a smooth plane quartic, can
one reconstruct the quartic?".
We use an isomorphism of two moduli problems, and the recent
classification of 2-transitive groups, to give an affirmative answer to
this question.

Due to the fast, there will be no formal refreshments before the colloquium.
