DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CGP-MP/25/">
 Mirror symmetry for a cusp polynomial Landau-Ginzburg orbifold</a>\nby Ale
 xey Basalaev (HSE & Skoltech) as part of IBS-CGP Mathematical Physics Semi
 nar\n\n\nAbstract\nWe will establish mirror symmetry between the cusp poly
 nomials considered with a nontrivial symmetry group and Geigle-Lenzing orb
 ifold projective lines. In particular\, we will introduce Dubrovin-Frobeni
 us manifold of equivariant Saito theory of any cusp polynomial and show th
 at it is isomorphic to Dubrovin-Frobenius manifold of the respective Geigl
 e-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
 ).\n
