 i/2/">Matrix factorizations and mirror symmetry</a>\nby Kazushi Ueda (Univ
 ersity of Tokyo) as part of Moduli spaces seminar\n\n\nAbstract\nHomologic
 al mirror symmetry is a conjecture introduced by Kontsevich which relates 
 the Fukaya category of a symplectic manifold with the derived category of 
 coherent sheaves on its mirror.  When the symplectic manifold is not Calab
 i-Yau\, the mirror is often described by matrix factorizations.  In the ta
 lk\, I will discuss a joint work with Yanki Lekili on homological mirror s
 ymmetry for Milnor fibers of invertible polynomials.\n

 i/3/">CFT\, BCFT\, VOA and all that.</a>\nby David Ridout (University of M
 elbourne) as part of Moduli spaces seminar\n\n\nAbstract\nFollowing on fro
 m Johanna Knapp's April 29 talk\, I will discuss some of the aspects of co
 nformal field theory (CFT) that are important for the LG/CFT correspondenc
 e.  This includes vertex operator algebras (VOAs)\, rationality\, the Verl
 inde formula and the corresponding Frobenius algebra\, boundary conformal 
 field theory (BCFT) and Ishibashi/Cardy states. Throughout\, the main exam
 ple will be the CFT corresponding to the A-type singularity with $W=x^d$.\

 i/4/">Categorical primitive forms and Frobenius manifolds</a>\nby Junwu Tu
  (ShanghaiTech 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 of singularity theory.  Saito’s theory has found a renewed interes
 t due to its natural appearance in mirror symmetry as the mirror dual of g
 enus zero Gromov-Witten theory.  Categorical primitive forms naturally gen
 eralize Saito’s definition to the categorical setup.  In particular\, it
  enables the construction of a (formal) Frobenius manifold structure natur
 ally associated to certain Calabi-Yau type categories.\n

 i/5/">FJRW theories of simple-elliptic singularities</a>\nby Alexey Basala
 ev (Skolkovo Institute of Science and Technology\, Moscow.) as part of Mod
 uli spaces seminar\n\n\nAbstract\nGiven a hypersurface singularity f toget
 her with some group of symmetries G\, FJRW theory produces the so-called A
 -side Landau-Ginzburg model.  From the perspective of mirror symmetry thi
 s is an A-side CohFT built by a pair (f\,G).  Mirror symmetry conjectures
  that it is isomorphic to a B-side CohFT of another pair (f'\,G') after a 
 good choice of a primitive form.\n\nIn this talk we will review FJRW theor
 ies of simple-elliptic singularities and provide the Frobenius manifold po
 tentials of them. We will also present the CY/LG correspondence result\, c
 onnecting such FJRW theories with Gromov-Witten theories of elliptic orbif
 olds.\n\nNote unusual time.\n
