Cost-sharing in Parking Games [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
In this paper, we study the total displacement statistic of parking functions from the perspective of cooperative game theory. We introduce parking games, which are coalitional cost-sharing games in characteristic function form derived from the total ...

Some exactly solvable models of urn process theory [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
We establish a fundamental isomorphism between discrete-time balanced urn processes and certain ordinary differential systems, which are nonlinear, autonomous, and of a simple monomial form.

Subcritical pattern languages for and/or trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
Let $P_k(f)$ denote the density of and/or trees defining a boolean function $f$ within the set of and/or trees with fixed number of variables $k$. We prove that there exists constant $B_f$ such that $P_k(f) \sim B_f \cdot k^{-L(f)-1}$ when $k \to \infty$,

Multivariate generalizations of the Foata-Schützenberger equidistribution [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
A result of Foata and Schützenberger states that two statistics on permutations, the number of inversions and the inverse major index, have the same distribution on a descent class.

Lasserre Hierarchy for Graph Isomorphism and Homomorphism Indistinguishability [PDF]

open access: yesTheoretiCS
We show that feasibility of the $t^\text{th}$ level of the Lasserre semidefinite programming hierarchy for graph isomorphism can be expressed as a homomorphism indistinguishability relation.

On the 2-adic order of Stirling numbers of the second kind and their differences [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2009
Let $n$ and $k$ be positive integers, $d(k)$ and $\nu_2(k)$ denote the number of ones in the binary representation of $k$ and the highest power of two dividing $k$, respectively.

Mixed Steiner Triple Systems With Shortest Length

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT A mixed Steiner triple system is a 3‐GDD which is viewed as a code with minimum Hamming distance 3. These codes are the minimum weight codewords of a 1‐perfect code over a mixed alphabet, when the related codes exist, and provide the connection between 3‐GDDs and coding theory.

Discrete spherical means of directional derivatives and Veronese maps [PDF]

open access: yes, 2011
We describe and study geometric properties of discrete circular and spherical means of directional derivatives of functions, as well as discrete approximations of higher order differential operators.
