There are two approaches to projective representation theory of symmetric and alternating groups, which are powerful enough to work for modular representations. One is based on Sergeev duality, which connects projective representation theory of the symmetric group and representation theory of the algebraic supergroup $Q(n)$ via appropriate Schur (super)algebras and Schur functors. The second approach follows the work of Grojnowski for classical affine and cyclotomic Hecke algebras and connects… 
Representations of Symmetric Groups
This chapter gives an overview of the representation theory of symmetric groups. We start with the characteristic 0 theory. The hook length formula gives the irreducible character degrees for
Modular spin characters of symmetric groups
The dissertation is concerned with concrete computations of modular spin characters of symmetric and alternating groups. We calculate all irreducible p-modular spin characters of the symmetric group
Highest weight sl_2-categorifications I: crystals
We define highest weight categorical actions of sl_2 on highest weight categories and show that basically all known examples of categorical sl_2-actions on highest weight categories (including
Small-dimensional projective representations of symmetric and alternating groups
We classify the irreducible projective representations of symmetric and alternating groups of minimal possible and second minimal possible dimensions, and get a lower bound for the third minimal
Highest weight $$\mathfrak{sl }_2$$-categorifications I: crystals
We define highest weight categorical actions of $$\mathfrak{sl }_2$$ on highest weight categories and show that basically all known examples of categorical $$\mathfrak{sl }_2$$-actions on highest
Composition factors of 2-parts spin representations of symmetric groups
Given an odd prime $p$, we identify composition factors of the reduction modulo $p$ of spin irreducible representations of the covering groups of symmetric groups indexed by partitions with 2 parts
Irreducible tensor products of representations of covering groups of symmetric and alternating groups
In this paper we completely classify irreducible tensor products of covering groups of symmetric and alternating groups in characteristic $\not=2$.
Torsion Free Sheaves on Weierstrass Cubic Curves and the Classical Yang–Baxter Equation
This work deals with an algebro–geometric theory of solutions of the classical Yang–Baxter equation based on torsion free coherent sheaves of Lie algebras on Weierstraß cubic curves.

Restricting Modular Spin Representations of Symmetric and Alternating Groups to Young‐Type Subgroups
Let F be an algebraically closed field of characteristic p, and let H be a finite group. A natural and important problem in representation theory is to classify the pairs (G, D), where G is a

In this article, we determine the irreducible projective representations of the symmetric group Sd and the alternating group Ad over an algebraically closed field of characteristic p 6= 2. These

Asymptotic Results on Modular Representations of Symmetric Groups and Almost Simple Modular Group Algebras
In fact, this is a question about infinite simple groups because it is easy for G finite, and because a non-trivial normal subgroup gives rise to a non-trivial ideal different from the augmentation
