The Relative Lie Algebra Cohomology of the Weil Representation

Jacob Ralston

We study the relative Lie algebra cohomology of with values in the Weil representation of the dual pair $\mathrm{Sp}(2k, \mathbb{R}) \times \mathrm{O}…

The Noether-Lefschetz conjecture and generalizations

Nicolas Bergeron, Zhiyuan Li, John Millson +1

We prove the Noether-Lefschetz conjecture on the moduli space of quasi-polarized K3 surfaces. This is deduced as a particular case of a general theorem that states that low degree…

The Relative Lie Algebra Cohomology of the Weil Representation of SO(n,1)

Nicolas Bergeron, John J. Millson, Jacob Ralston

In Part 1 of this paper we construct a spectral sequence converging to the relative Lie algebra cohomology associated to the action of any subgroup of the symplectic group on t…

The Hodge conjecture and arithmetic quotients of complex balls

Nicolas Bergeron, John Millson, Colette Moeglin

Let be a closed Shimura variety uniformized by the complex -ball. The Hodge conjecture predicts that every Hodge class in $H^{2k} (S, \Q)$, , is algebraic. W…

On representation varieties of 3-manifold groups

John J. Millson, Michael Kapovich

We prove universality theorems ("Murphy's Laws") for representation schemes of fundamental groups of closed 3-dimensional manifolds. We show that germs of SL(2,C)-representation sc…

Hodge type theorems for arithmetic manifolds associated to orthogonal groups

Nicolas Bergeron, John Millson, Colette Moeglin

We show that special cycles generate a large part of the cohomology of locally symmetric spaces associated to orthogonal groups. We prove in particular that classes of totally geod…
