DESCRIPTION:Title: Top weight cohomology of A_g\nby Juliette Bruce (Brown
University) as part of Harvard MIT Algebraic Geometry Seminar\n\nLecture h
eld in Harvard Science Center 507.\n\nAbstract\nI will discuss recent work
calculating the top weight cohomology of the moduli space A_g of principa
lly polarized abelian varieties of dimension g for small values of g. The
key idea is that this piece of cohomology is encoded combinatorially via t
he relationship between the boundary complex of a compactification of A_g
and the moduli space of tropical abelian varieties. This is joint work wit
h Madeline Brandt\, Melody Chan\, Margarida Melo\, Gwyneth Moreland\, and
Corey Wolfe.\n

DESCRIPTION:Title: Cohomological Donaldson-Thomas theory for 2-Calabi--Yau cat
egories\nby Tasuki Kinjo (University of Tokyo) as part of Harvard MIT
Algebraic Geometry Seminar\n\nLecture held in MIT 2-132.\n\nAbstract\nCoho
mological Donaldson-Thomas (CoDT) invariants were introduced by Kontsevich
-Soibelman and Brav-Bussi-Dupont-Joyce-Szendroi as categorifications of th
e Donaldson-Thomas invariants counting objects in 3-Calabi-Yau categories.
In this talk\, I will explain applications of the CoDT theory to the coho
mological study of the moduli of objects in 2-Calabi-Yau categories. Among
other things\, I will construct a coproduct on the Borel-Moore homology o
f the moduli stack of objects in these categories and establish a PBW-type
statement for the Kapranov-Vasserot cohomological Hall algebras. This tal
k is based on a joint work in progress with Ben Davison.\n

DESCRIPTION:Title: On the invariance of Hodge numbers under derived equivalenc
e\nby Luigi Lombardi (University of Milan) as part of Harvard MIT Alge
braic Geometry Seminar\n\nLecture held in Harvard Science Center 507.\n\nA
bstract\nA conjecture of Orlov predicts the invariance of the Hodge number
s of a smooth projective complex variety under derived equivalence. For in
stance this has been verified in the case of varieties of general type. In
this talk\, I will examine the case of varieties that are fibered by vari
eties of general type through the Albanese map. For this class of varietie
s I will prove the derived invariance of Hodge numbers of type $h^{0\,p}$\
, together with a few other invariants arising from the Albanese map. This
talk is based on a joint work with F. Caucci and G. Pareschi.\n

DESCRIPTION:Title: The Chow ring of the moduli space of degree 2 K3 surfaces\nby Samir Canning (ETH Zurich) as part of Harvard MIT Algebraic Geometr
y Seminar\n\nLecture held in Harvard Science Center 507.\n\nAbstract\nThe
intersection theory of the moduli space of K3 surfaces polarized by a latt
ice is a subject of recent interest because of its deep connections with a
wide variety of mathematics\, including the intersection theory of moduli
spaces of curves and the study of modular forms. Oprea and Pandharipande
conjectured that the tautological rings of these moduli spaces of K3 surfa
ces are highly structured in a way that mirrors the picture for the moduli
space of curves. I will discuss the proof of this conjecture in the case
of K3 surfaces polarized by a degree 2 line bundle. This is joint work wit
h Dragos Oprea and Rahul Pandharipande.\n

DESCRIPTION:Title: Kodaira dimension and hyperbolicity for smooth families of
varieties\nby Sung Gi Park (Harvard University) as part of Harvard MIT
Algebraic Geometry Seminar\n\nLecture held in MIT 2-132.\n\nAbstract\nIn
this talk\, I will discuss the behavior of positivity\, hyperbolicity\, an
d Kodaira dimension under smooth morphisms of complex quasi-projective man
ifolds. This includes a vast generalization of a classical result: a fibra
tion from a projective surface of non-negative Kodaira dimension to a proj
ective line has at least three singular fibers. Furthermore\, I will expla
in a proof of Popa's conjecture on the superadditivity of the log Kodaira
dimension over bases of dimension at most three. These theorems are applic
ations of the main technical result\, namely the logarithmic base change t
heorem.\n
