Number conserving cellular automata: new results on decidability and dynamics [PDF]
Discrete Mathematics & Theoretical Computer Science, 2003 This paper is a survey on our recent results about number conserving cellular automata. First, we prove the linear time decidability of the property of number conservation. The sequel focuses on dynamical evolutions of number conserving cellular automata.

Rainbow perfect matchings in r-partite graph structures [PDF]
, 2016 A matching M in an edge–colored (hyper)graph is rainbow if each pair of edges in M have distinct colors. We extend the result of Erdos and Spencer on the existence of rainbow perfect matchings in the complete bipartite graph Kn,n to complete bipartite ...

Some exactly solvable models of urn process theory [PDF]
Discrete 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]
Discrete 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 $k \to \infty$,

Cost-sharing in Parking Games [PDF]
Discrete Mathematics & Theoretical Computer ScienceIn 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 ...

Multivariate generalizations of the Foata-Schützenberger equidistribution [PDF]
Discrete 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.

Some remarks on multiplicity codes
, 2014 Multiplicity codes are algebraic error-correcting codes generalizing classical polynomial evaluation codes, and are based on evaluating polynomials and their derivatives.

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

Tiling a Rectangle with Polyominoes [PDF]
Discrete Mathematics & Theoretical Computer Science, 2003 A polycube in dimension $d$ is a finite union of unit $d$-cubes whose vertices are on knots of the lattice $\mathbb{Z}^d$. We show that, for each family of polycubes $E$, there exists a finite set $F$ of bricks (parallelepiped rectangles) such that the ...
