A new family of isolated symplectic singularities with trivial local fundamental group

Gwyn Bellamy, Cédric Bonnafé, Baohua Fu +3

We construct a new infinite family of 4-dimensional isolated symplectic singularities with trivial local fundamental group, answering a question of Beauville raised in 2000. Three…

Complex reflection groups and K3 surfaces II. The groups , and

Cédric Bonnafé, Alessandra Sarti

We study some K3 surfaces obtained as minimal resolutions of quotients of subgroups of special reflection groups. Some of these were already studied in a previous paper by W. Barth…

Computational aspects of Calogero-Moser spaces

Cédric Bonnafé, Ulrich Thiel

We present a series of algorithms for computing geometric and representation-theoretic invariants of Calogero-Moser spaces and rational Cherednik algebras associated to complex ref…

Calogero-Moser spaces vs unipotent representations

Cédric Bonnafé

Lusztig's classification of unipotent representations of finite reductive groups depends only on the associated Weyl group (endowed with its Frobenius automorphism). All the st…

The Tate and Standard Conjectures for Certain Abelian Varieties

James S. Milne

In two earlier articles, we proved that, if the Hodge conjecture is true for ALL CM abelian varieties over the complex numbers, then both the Tate conjecture and the standard conje…

Automorphisms and symplectic leaves of Calogero-Moser spaces

Cédric Bonnafé

We study the symplectic leaves of the subvariety of fixed points of an automorphism of a Calogero-Moser space induced by an element of finite order of the normalizer of the associa…
