Subfitness in distributive (semi)lattices
Guram Bezhanishvili, James Madden, M. Andrew Moshier +2
We investigate whether the set of subfit elements of a distributive semilattice is an ideal. This question was raised by the second author at the BLAST conference in 2022. We show…
Conjunctive Join Semi-Lattices
Charles N. Delzell, Oghenetega Ighedo, James J. Madden
A join-semilattice is said to be conjunctive if it has a top element and it satisfies the following first-order condition: for any two distinct , there is $c\in L…
A Generating Function for the Distribution of Runs in Binary Words
James J. Madden
Let denote the number of binary words of length that begin with and contain exactly runs (i.e., maximal subwords of identical consecutive symbols) of length…
Local Finiteness of Infinite Neighbor Complexes
James J. Madden
We show that if the neighbor complex, as defined by H.~Scarf, of an infinite subset of has finite dimension, then each vertex has finitely many neighbors.
Neighbors, Generic Sets and Scarf-Buchberger Hypersurfaces
James J. Madden, Trevor McGuire
The present paper is motivated by the need to generalize the construction of the Scarf complex in order to give combinatorial resolutions of a much broader class of modules than ju…
Approximate roots of a valuation and the Pierce-Birkhoff Conjecture
François Lucas, James Madden, Daniel Schaub +1
This paper is a step in our program for proving the Piece-Birkhoff Conjecture for regular rings of any dimension (this would contain, in particular, the classical Pierce-Birkhoff c…
