Combinatorial representation theory of Lie algebras. Richard Stanley's work and the way it was continued [PDF]

, 2014
Richard Stanley played a crucial role, through his work and his students, in the development of the relatively new area known as combinatorial representation theory.

Kleinian Singularities: Some Geometry, Combinatorics and Representation Theory [PDF]

Jahresbericht Der Deutschen Mathematiker-vereinigung
We review the relationship between discrete groups of symmetries of Euclidean three-space, constructions in algebraic geometry around Kleinian singularities including versions of Hilbert and Quot schemes, and their relationship to finite-dimensional and ...

Black Holes as Quantum Gravity Condensates [PDF]

, 2018
We model spherically symmetric black holes within the group field theory formalism for quantum gravity via generalised condensate states, involving sums over arbitrarily refined graphs (dual to 3d triangulations).

On the enumeration of closures and environments with an application to random generation [PDF]

, 2019
Environments and closures are two of the main ingredients of evaluation in lambda-calculus. A closure is a pair consisting of a lambda-term and an environment, whereas an environment is a list of lambda-terms assigned to free variables.

A Characterization of Uniquely Representable Graphs [PDF]

, 2020
The betweenness structure of a finite metric space $M = (X, d)$ is a pair $\mathcal{B}(M) = (X,\beta_M)$ where $\beta_M$ is the so-called betweenness relation of $M$ that consists of point triplets $(x, y, z)$ such that $d(x, z) = d(x, y) + d(y, z)$. The

Wick's theorem for q-deformed boson operators [PDF]

, 2007
In this paper combinatorial aspects of normal ordering arbitrary words in the creation and annihilation operators of the q-deformed boson are discussed.

The Tensor Track, III [PDF]

, 2013
We provide an informal up-to-date review of the tensor track approach to quantum gravity. In a long introduction we describe in simple terms the motivations for this approach.

On Non Commutative G2 structure

, 2005
Using an algebraic orbifold method, we present non-commutative aspects of $G_2$ structure of seven dimensional real manifolds. We first develop and solve the non commutativity parameter constraint equations defining $G_2$ manifold algebras.

Fractional Statistics in terms of the r-Generalized Fibonacci Sequences [PDF]

, 2001
We develop the basis of the two dimensional generalized quantum statistical systems by using results on $r$-generalized Fibonacci sequences. According to the spin value $s$ of the 2d-quasiparticles, we distinguish four classes of quantum statistical ...

Higher-Order Quantum-Inspired Genetic Algorithms [PDF]

, 2014
This paper presents a theory and an empirical evaluation of Higher-Order Quantum-Inspired Genetic Algorithms. Fundamental notions of the theory have been introduced, and a novel Order-2 Quantum-Inspired Genetic Algorithm (QIGA2) has been presented ...
