A new proof of the Mullineux conjecture
 Journal of Algebraic Combinatorics
"... Let Sn be the symmetric group on n letters, k be a field of characteristic p and Dλ be the irreducible kSnmodule corresponding to a pregular partition λ of n, as in [12]. By tensoring Dλ with the 1dimensional sign representation we obtain another irreducible kSnmodule. If p = 0, Dλ ⊗ sgn ∼ = Dλ ..."

REPRESENTATIONS OF LIE SUPERALGEBRAS IN PRIME CHARACTERISTIC II: THE QUEER SERIES
, 902
"... Abstract. The modular representation theory of the queer Lie superalgebra q(n) over characteristic p> 2 is developed. We obtain a criterion for the irreducibility of baby Verma modules with semisimple pcharacters χ and a criterion for the semisimplicity of the corresponding reduced enveloping al ..."

Abstract. The modular representation theory of the queer Lie superalgebra q(n) over characteristic p> 2 is developed. We obtain a criterion for the irreducibility of baby Verma modules with semisimple pcharacters χ and a criterion for the semisimplicity of the corresponding reduced enveloping algebras Uχ(q(n)). A (2p)power divisibility of dimensions of q(n)modules with nilpotent pcharacters is established. The representation theory of q(2) is treated in detail. We formulate a Morita superequivalence conjecture for q(n) with general pcharacters which is verified for n = 2. Contents
Chevalley supergroups

In the framework of algebraic supergeometry, we give a construction of the schemetheoretic supergeometric analogue of Chevalley groups, namely affine algebraic supergroups associated to simple Lie superalgebras of classical type. This provides a unified approach to most of the algebraic supergroups considered so far in literature, and an effective method to construct new ones. As an intermediate step, we prove an existence theorem for Chevalley bases of simple classical Lie superalgebras and a PBWlike theorem for their associated Kostant superalgebras.

ON THE CONSTRUCTION OF CHEVALLEY SUPERGROUPS
"... We give a description of the construction of Chevalley supergroups, providing some explanatory examples. We avoid the discussion of the A(1; 1), P (3) and Q(n) cases, for which our construction holds, but the exposigetion becomes more complicated. We shall not in general provide complete proofs for ..."

We give a description of the construction of Chevalley supergroups, providing some explanatory examples. We avoid the discussion of the A(1; 1), P (3) and Q(n) cases, for which our construction holds, but the exposigetion becomes more complicated. We shall not in general provide complete proofs for our statements, instead we will make an effort to convey the key ideas underlying our construction. A fully detailed account of our work is scheduled to appear in [9]. 1

Associated to the two types of finitedimensional simple superalgebras, there are the general linear Lie superalgebra and the queer Lie superalgebra. The universal enveloping algebras of these Lie superalgebras act on the tensor spaces of the natural representations and, thus, define certain finitedimensional quotients, the Schur superalgebras, and the queer Schur superalgebra. In this paper, we introduce the quantum analog of the queer Schur superalgebra and investigate the presentation problem for both the queer Schur superalgebra and its quantum analog. 1
