An Inequality for Tactical Configurations
This note is devoted to proving a theorem and a generalisation of it which were originally suggested by our group-theoretical studies but which in fact are purely combinatorial. After it was accepted for publication, we learned that the theorems are not new, although our proofs appear to be substantially simpler than those appearing elsewhere. We had checked the literature on combinatorial desi...
متن کاملOn Tactical Configurations with No Four-Cycles
An improved lower bound is given for the band sizes of tactical configurations of rank exceeding two having no 4-cycles. This bound is applied to find an optimal configuration with certain specified parameters. A formula is given for the maximum number of cycle types one must examine to demonstrate that a rank Y configuration has no g-cycle. This result, which has appeared in our earlier work a...
متن کاملTactical Configurations and Their Generic Ring
A construction of Tits is used to cast the argument of Kilmoyer-Solomon and Higman proving the Feit-Higman theorem in the context of tactical configurations. An analog of a result of Cvetkovic shows what combinatorial data is needed to determine the representations associated with a given configuration. The possible representations fall into three types. A bound is given for the size of certain...
متن کاملMulticomponent Distillation Configurations with Large Energy Savings
In industry, many separation processes involve the separation of multicomponent mixtures using distillation. There are many distillation configurations that can carry out the same overall separation process. These configurations use an equal number of distillation columns, but they differ significantly in energy consumption. Therefore a major challenge for a practitioner is the identification o...
متن کاملVortex configurations in the large N limit
We study the properties of vortex-like configurations which are solutions of the SU(N) Yang-Mills classical equations of motion. We show that these solutions are concentrated along a two-dimensional wall with size growing with the number of colors. PACS: 11.15.-q, 11.15.Ha
