Algebra, coding theory, and cryptography
Research Interests
My area of expertise is algebraic combinatorics. More precisely,
my doctoral thesis concentrated on Solomon descent algebras of Coxeter
groups with a particular focus on their multiplicative structure, and
the
establishment of their basic algebraic structure and representation
theory
over fields of finite characteristic.
Since then, I have been interested in Pieri operators on
posets, a series of
operators
that have been seen to link the diverse areas of Schubert calculus,
combinatorics
of polytopes, and P-partitions, amongst others. This led to the study
of ribbon Schur function equality.
Of late, I have generalised this study to skew Schur function
equality and applied the knowledge gleaned to the study of Schur
positivity.
Most recently, I have been studying a natural quasisymmetric
refinement of Schur functions that reflect many of the properties
displayed by Schur functions.
Keywords and phrases Coxeter
group, representation
theory, finite fields, P-partition, Pieri formula, graded
operation on posets, cd-index, quasisymmetric function, Schur
function, Macdonald polynomial.
