Character sheaves and modular representations of finite reductive groups [PDF]
In this thesis, we study finite reductive groups and their modular representations in non-defining characteristic. In 1990, Geck stated a conjecture on the unitriangularity of decomposition matrices of these groups. Decomposition matrices encode the link between ordinary representations (over a field of characteristic zero) and modular ...

Modular transformations of admissible N = 2 and Affine sl(2|1;C) characters [PDF]
, 2002 This thesis is a study of the affine super-algebra sl(2|l; C) and N = 2 superconformal algebra at fractional levels. In the first chapter we review background material on Conformal Field Theory, and how it appears in the context of string theory and the ...

Higher level appell functions, modular transformations and non-unitary characters [PDF]
, 2003 In this thesis, we firstly extend elements and periodicity properties of the theta function theory to functions that represent a wider domain of symmetries and properties, graded with different amounts of p ≥ 1, p ϵ N.

Level-Raising for GSp(4) [PDF]
, 2006 This thesis provides congruences between unstable and stable automorphic forms for the symplectic similitude group $GSp(4)$. More precisely, we raise the level of certain CAP representations $Pi$ of Saito-Kurokawa type, arising from classical modular ...

Artin L-Functions for Abelian Extensions of Imaginary Quadratic Fields [PDF]
, 2005 Let F be an abelian extension of an imaginary quadratic field K with Galois group G. We form the Galois-equivariant L-function of the motive h(Spec F)(j) where the Tate twists j are negative integers.

Representation zeta functions of compact p-adic analytic groups and arithmetic groups [PDF]
, 2013 We introduce new methods from p-adic integration into the study of representation zeta functions associated to compact p-adic analytic groups and arithmetic groups.

Higher-Level Appell Functions, Modular Transformations, and Characters [PDF]
, 2005 We study modular transformation properties of a class of indefinite theta series involved in characters of infinite-dimensional Lie superalgebras. The level- Appell functions satisfy open quasiperiodicity relations with additive theta-function terms ...

The maximal subgroups of the classical groups in dimension 13, 14 and 15 [PDF]
, 2015 One might easily argue that the Classification of Finite Simple Groups is one of the most important theorems of group theory. Given that any finite group can be deconstructed into its simple composition factors, it is of great importance to have a ...
