The excedance quotient of the Bruhat order, quasisymmetric varieties, and Temperley–Lieb algebras
Journal of the London Mathematical Society, Volume 110, Issue 4, October 2024.Abstract Let Rn=Q[x1,x2,…,xn]$R_n=\mathbb {Q}[x_1,x_2,\ldots ,x_n]$ be the ring of polynomials in n$n$ variables and consider the ideal ⟨QSymn+⟩⊆Rn$\langle \mathrm{QSym}_{n}^{+}\rangle \subseteq R_n$ generated by quasisymmetric polynomials without constant term. It was shown by J. C. Aval, F. Bergeron, and N. Bergeron that dim(Rn/⟨QSymn+⟩)=Cn$\dim \big

IET Intelligent Transport Systems, Volume 18, Issue 6, Page 1121-1136, June 2024.When automatic‐driving cars perform path planning in a road environment, the sensing range of a single vehicle is limited, resulting in an insufficiently smooth planned path. In response to the aforementioned issues, this paper proposes a path planning method based on multi‐vehicle collaborative mapping in the context of vehicular networks.

Alexander Duality and Rational Associahedra [PDF]
, 2013 A recent pair of papers of Armstrong, Loehr, and Warrington and Armstrong, Williams, and the author initiated the systematic study of {\em rational Catalan combinatorics} which is a generalization of Fuss-Catalan combinatorics (which is in turn a ...

How vulnerable is an undirected planar graph with respect to max flow
Networks, Volume 83, Issue 3, Page 570-586, April 2024.Abstract We study the problem of computing the vitality of edges and vertices with respect to the st$$ st $$‐max flow in undirected planar graphs, where the vitality of an edge/vertex is the st$$ st $$‐max flow decrease when the edge/vertex is removed from the graph. This allows us to establish the vulnerability of the graph with respect to the st$$ st

On Rees algebras of 2‐determinantal ideals
Journal of the London Mathematical Society, Volume 109, Issue 1, January 2024.Abstract Let I$I$ be the ideal of minors of a 2×n$2 \times n$ matrix of linear forms with the expected codimension. In this paper, we prove that the Rees algebra of I$I$ and its special fiber ring are Cohen–Macaulay and Koszul; in particular, they are quadratic algebras.

Semigroups of distributions with linear Jacobi parameters
, 2011 We show that a convolution semigroup of measures has Jacobi parameters polynomial in the convolution parameter $t$ if and only if the measures come from the Meixner class.

On divisibility of Narayana numbers by primes
, 2005 Using Kummer's Theorem, we give a necessary and sufficient condition for a Narayana number to be divisible by a given prime. We use this to derive certain properties of the Narayana triangle.Comment: 5 pages, see related papers at http://www.math.msu.edu/
