The Mathematical center in Akademgorodok invites you to take part in the
"Beijing-Novosibirsk seminar on geometry and mathematical physics" on
June 10 at 4 pm Novosibirsk time (UTC+7).
The seminar's heads: A. E. Mironov, I. A. Taimanov, Huijun Fan, Youjin Zhang.
During the seminar
Alexey A. Basalaev (HSE, Moscow) will present his talk
"Mirror symmetry for a cusp polynomial Landau-Ginzburg orbifold".
We will establish mirror symmetry between the cusp polynomials considered with a nontrivial symmetry group and Geigle-Lenzing orbifold projective lines. In particular, we will introduce Dubrovin-Frobenius manifold of equivariant Saito theory of any cusp polynomial and show that it is isomorphic to Dubrovin-Frobenius manifold of the respective Geigle-Lenzing orbifold.
We will also show that in the case of simple-elliptic singularities this mirror isomorphism is equivalent the certain relations in the ring of modular forms.
This is a joint work with A.Takahashi (Osaka).
To take part, please, on June 10 after 3:45 pm Novosibirsk time (UTC+7) connect to the Zoom conference via this link:
