Dear all, Some of you may be interested in the preprint: 05.03 EHLERS, P.J. & PORTER, T. Ordinal subdivision and special pasting in quasicategories Abstract: Quasicategories are simplicial sets with properties generalising those of the nerve of a category. They model weak infinity-categories. Using a combinatorially defined ordinal subdivision, we examine composition rules for certain special pasting diagrams in quasicategories. The subdivision is of combinatorial interest in its own right and is linked with various combinatorial constructions.
