چکیده
We study the combinatorics of fully commutative elements in Coxeter groups of type H n for any n > 2. Using the results, we construct certain canonical bases for non-simply-laced generalized Temperley–Lieb algebras and show how to relate them to morphisms in the category of decorated tangles.

Decorated Tangles and Canonical Bases
We study the combinatorics of fully commutative elements in Coxeter groups of type H n for any n > 2. Using the results, we construct certain canonical bases for non-simply-laced generalized Temperley{Lieb algebras and show how to relate them to morphisms in the category of decorated tangles.
متن کاملWoven Geometries: Black Holes
Tangles of loops which approximate an aspect of the Kerr-Newman black hole metrics at large scales compared to the Planck length are constructed. The physical aspect the tangles approximate is discussed. This construction may be useful in the loop representation of canonical quantum gravity. Implications and applications of the tangles are remarked.
متن کاملTangled up in Blue (A Survey on Connectivity, Decompositions, and Tangles)
We survey an abstract theory of connectivity, based on symmetric submodular set functions. We start by developing Robertson and Seymour’s [44] fundamental duality theory between branch decompositions (related to the better-known tree decompositions) and so-called tangles, which may be viewed as highly connected regions in a connectivity system. We move on to studying canonical decompositions of...
متن کاملRole of Presenilin-1 in Modulating Glycogen Synthase Kinase 3 β Expression in the Pathogenesis of Alzheimer’s Disease
Context: Alzheimer’s disease (AD) is a neurodegenerative disorder that is characterized by the presence of neurofibrillary tangles (NFT) and senile plaques caused due to amyloid beta (Aβ) peptide localization in the brain. Evidence Acquisition: Proteolytic cleavage of the amyloid precursor protein (APP) results in the formation of the Aβ plaques via the sequential action of the β – secretase an...
متن کاملChord diagram invariants of tangles and graphs
The notion of a chord diagram emerged from Vassiliev's work Vas90], Vas92] (see also Gusarov Gus91], Gus94] and Bar-Natan BN91], BN95]). Slightly later, Kontsevich Kon93] deened an invariant of classical knots taking values in the algebra generated by formal linear combinations of chord diagrams modulo the four-term relation. This knot invariant establishes an isomorphism of a projective limit ...
