DESCRIPTION:Title: M
atrix factorizations and mirror symmetry\nby Kazushi Ueda (University
of Tokyo) as part of Moduli spaces seminar\n\n\nAbstract\nHomological mirr
or symmetry is a conjecture introduced by Kontsevich which relates the Fuk
aya category of a symplectic manifold with the derived category of coheren
t sheaves on its mirror. When the symplectic manifold is not Calabi-Yau\,
the mirror is often described by matrix factorizations. In the talk\, I
will discuss a joint work with Yanki Lekili on homological mirror symmetry
for Milnor fibers of invertible polynomials.\n

DESCRIPTION:Title: C
FT\, BCFT\, VOA and all that.\nby David Ridout (University of Melbourn
e) as part of Moduli spaces seminar\n\n\nAbstract\nFollowing on from Johan
na Knapp's April 29 talk\, I will discuss some of the aspects of conformal
field theory (CFT) that are important for the LG/CFT correspondence. Thi
s includes vertex operator algebras (VOAs)\, rationality\, the Verlinde fo
rmula and the corresponding Frobenius algebra\, boundary conformal field t
heory (BCFT) and Ishibashi/Cardy states. Throughout\, the main example wil
l be the CFT corresponding to the A-type singularity with $W=x^d$.\n

DESCRIPTION:Title: C
ategorical primitive forms and Frobenius manifolds\nby Junwu Tu (Shang
haiTech University) as part of Moduli spaces seminar\n\n\nAbstract\nIn the
1980’s K. Saito introduced the notion of primitive forms in his study o
f singularity theory. Saito’s theory has found a renewed interest due t
o its natural appearance in mirror symmetry as the mirror dual of genus ze
ro Gromov-Witten theory. Categorical primitive forms naturally generalize
Saito’s definition to the categorical setup. In particular\, it enable
s the construction of a (formal) Frobenius manifold structure naturally as
sociated to certain Calabi-Yau type categories.\n

DESCRIPTION:Title: F
JRW theories of simple-elliptic singularities\nby Alexey Basalaev (Sko
lkovo Institute of Science and Technology\, Moscow.) as part of Moduli spa
ces seminar\n\n\nAbstract\nGiven a hypersurface singularity f together wit
h some group of symmetries G\, FJRW theory produces the so-called A-side L
andau-Ginzburg model. From the perspective of mirror symmetry this is an
A-side CohFT built by a pair (f\,G). Mirror symmetry conjectures that i
t is isomorphic to a B-side CohFT of another pair (f'\,G') after a good ch
oice of a primitive form.\n\nIn this talk we will review FJRW theories of
simple-elliptic singularities and provide the Frobenius manifold potential
s of them. We will also present the CY/LG correspondence result\, connecti
ng such FJRW theories with Gromov-Witten theories of elliptic orbifolds.\n
\nNote unusual time.\n
