DESCRIPTION:In mirror symmetry\, we aim to build a relationshi
p between the enumerative geometry of a symplectic
manifold and period integrals on its mirror manif
old. This relationship has been extended in the pa
st 15 years to Landau-Ginzburg models. Roughly\, a
Landau-Ginzburg (LG) model is a triplet of data (
X\, G\, W) where X is a quasi-affine variety\, G i
s a group acting on X and W is a G-invariant compl
ex-valued algebraic function from X to the complex
numbers. Mirror symmetry relates the enumerative
geometry of an LG model (so-called Fan-Jarvis-Ruan
-Witten theory) to a system of oscillatory integra
ls on the mirror that serve as period integrals (s
o-called Saito-Givental theory). Recently\, there
has been progress in constructing open invariants
on both sides of the mirror symmetry correspondenc
e in these cases. We how this works for Fermat pol
ynomials based on work with Mark Gross and Ran Tes
sler\, with an emphasis on the period-style comput
ations as they are more in line with the theme of
the workshop.
