Decorated tangles and canonical bases

[摘要] 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.
