One hundred and fourteen isolates of Verticillium dahliae obtained from cotton and eggplant in mainland China were successfully assigned to two vegetative compatibility groups (VCGs) except for oneâ€¦ (More)

We introduce the notion of a baric structure on a triangulated category, as an abstraction of S. Morelâ€™s weight truncation formalism for mixed `-adic sheaves. We study these structures on the derivedâ€¦ (More)

We study the Lusztig-Vogan bijection for the case of a local system. We compute the bijection explicitly in type A for a local system and then show that the dominant weights obtained for differentâ€¦ (More)

We define a partial order on the set No,cÌ„ of pairs (O, C), where O is a nilpotent orbit and C is a conjugacy class in Ä€(O), Lusztigâ€™s canonical quotient of A(O). We then construct an order-reversingâ€¦ (More)

Let G be a simple complex algebraic group. Lusztig and Vogan have conjectured the existence of a natural bijection between the set of dominant integral weights of G, and the set of pairs consistingâ€¦ (More)

We show that two Weyl group actions on the Springer sheaf with arbitrary coefficients, one defined by Fourier transform and one by restriction, agree up to a twist by the sign character. Thisâ€¦ (More)

The classical Frobeniusâ€“Schur indicators for finite groups are character sums defined for any representation and any integer m â‰¥ 2. In the familiar case m = 2, the Frobeniusâ€“Schur indicatorâ€¦ (More)

We compare orbits in the nilpotent cone of type Bn, that of type Cn, and Katoâ€™s exotic nilpotent cone. We prove that the number of Fq-points in each nilpotent orbit of type Bn or Cn equals that in aâ€¦ (More)

Let X be a scheme of finite type over a Noetherian base scheme S admitting a dualizing complex, and let U âŠ‚ X be an open set whose complement has codimension at least 2. We extend the theory ofâ€¦ (More)

In characteristic zero, Bezrukavnikov has shown that the category of perverse coherent sheaves on the nilpotent cone of a simply connected semisimple algebraic group is quasi-hereditary, and that itâ€¦ (More)
