A bijection between noncrossing and nonnesting partitions of types A and B [PDF]
Discrete Mathematics & Theoretical Computer Science, 2009 The total number of noncrossing partitions of type $\Psi$ is the $n$th Catalan number $\frac{1}{ n+1} \binom{2n}{n}$ when $\Psi =A_{n-1}$, and the binomial coefficient $\binom{2n}{n}$ when $\Psi =B_n$, and these numbers coincide with the correspondent ...

Hyperbolic Structures and Root Systems [PDF]
, 2010 We discuss the construction of a one parameter family of complex hyperbolic structures on the complement of a toric mirror arrangement associated with a simply laced root system.

Non-orthogonal geometric realizations of Coxeter groups [PDF]
, 2012 We define in an axiomatic fashion a \emph{Coxeter datum} for an arbitrary Coxeter group $W$. This Coxeter datum will specify a pair of reflection representations of $W$ in two vector spaces linked only by a bilinear paring without any integrality and non-

Bernstein-Szego Polynomials Associated with Root Systems [PDF]
, 2007 We introduce multivariate generalizations of the Bernstein-Szego polynomials, which are associated to the root systems of the complex simple Lie algebras.

A simple and cost-effective method for cable root detection and extension measurement in estuary wetland forests [PDF]
, 2016 This work presents the development of a low-cost method to measure the length cable roots of black mangrove (Avicennia germinans) trees to define the boundaries of central part of the anchoring root system (CPRS) without the need to fully expose root ...

Generalised Calogero-Moser models and universal Lax pair operators [PDF]
, 1999 Calogero-Moser models can be generalised for all of the finite reflection groups. These include models based on non-crystallographic root systems, that is the root systems of the finite reflection groups, H_3, H_4, and the dihedral group I_2(m), besides ...
