Very roughly speaking, representation theory studies symmetry in linear spaces. It is a beautiful mathematical subject which has many applications, ranging from number theory and combinatorics to geometry, probability theory, quantum mechanics, and quantum field theory. The goal of this book is to give a "holistic" introduction to representation theory, presenting it as a unified subject which studies representations of associative algebras and treating the representation theories of groups…

Representation theory of algebras related to the partition algebra

The main objective of this thesis is to determine the complex generic representation theory of the Juyumaya algebra. We do this by showing that a certain specialization of this algebra is isomorphic

LECTURE 1: REPRESENTATIONS OF SYMMETRIC GROUPS, I

In this lecture we start to study the representation theory of the symmetric groups Sn over C. Let us summarize a few things that we already know. 0) A representation of Sn is the same thing as a

Counting representations of deformed preprojective algebras

For any given quiver Γ, there is a preprojective algebra and deformed preprojective algebras associated to it. If the ground field is of characteristic 0, then there are no finite dimensional

Signatures of Stable Multiplicity Spaces in Restrictions of Representations of Symmetric Groups

Representation theory is a way of studying complex mathematical structures such as groups and algebras by mapping them to linear actions on vector spaces. Recently, Deligne proposed a new way to

Invariants of Automorphic Lie Algebras

Automorphic Lie Algebras arise in the context of reduction groups introduced in the late 1970s [35] in the field of integrable systems. They are subalgebras of Lie algebras over a ring of rational

Almost settling the hardness of noncommutative determinant

TLDR
This paper studies the complexity of computing the determinant of a matrix over a noncommutative algebra and shows that if A/R(A) is commutative then efficient determinant computation is possible, and otherwise determinant is as hard as permanent.

A representation-theoretical solution to MathOverflow question #88399

Let us first reduce Theorem 1 to a representation-theoretical statement: For any finite group G, let Irrep G denote a set of representatives of all irreducible representations of G modulo isomorphy.

On the centralizer algebras of tensor products of irreducible Weyl modules

Tensor products of natural modules and their centralizers are well-studied in the literature. This thesis extends classical results to tensor products of irreducible Weyl modules over a quantum

Equivariantização de categorias k-lineares

The category theory is introduced for the rst time in 1945 in a research entitulated General Theory of Natural Equivalences. In 1950 in a publication called Duality for Groups, MacLane introduce

On the Green rings of pointed, coserial Hopf algebras

The Green ring is a powerful mathematical tool used to codify the interactions between representations of groups and algebras. This ring is spanned by isomorphism classes of finite-dimensional
