Enumerative and planar combinatorics of trivariate monomial resolutions

open access: yes, 2020
The canonical sylvan resolution is a resolution of an arbitrary monomial ideal over a polynomial ring that is minimal and has an explicit combinatorial formula for the differential. The differential is a weighted sum over lattice paths of weights of chain-link fences, which are sequences of faces that are linked to each other via higher-dimensional ...

Enumerative Combinatorics and Shannon's Theory of Discrete Noiseless Channels

open access: yesElectronic Notes in Discrete Mathematics, 2001
Abstract Abstract In this paper we demonstrate the application of combinatorial techniques as a way to finding the Shannon capacity of the discrete noiseless channel.
