On the density and the structure of the Peirce-like formulae [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
Within the language of propositional formulae built on implication and a finite number of variables $k$, we analyze the set of formulae which are classical tautologies but not intuitionistic (we call such formulae - Peirce's formulae).

On the number of zero increments of random walks with a barrier [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
Continuing the line of research initiated in Iksanov and Möhle (2008) and Negadajlov (2008) we investigate the asymptotic (as $n \to \infty$) behaviour of $V_n$ the number of zero increments before the absorption in a random walk with the barrier $n$. In

Volume Laws for Boxed Plane Partitions and Area Laws for Ferrers Diagrams [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
We asymptotically analyse the volume random variables of general, symmetric and cyclically symmetric plane partitions fitting inside a box. We consider the respective symmetry class equipped with the uniform distribution.

Product decomposition for surjective 2-block NCCA [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2011
In this paper we define products of one-dimensional Number Conserving Cellular Automata (NCCA) and show that surjective NCCA with 2 blocks (i.e radius 1/2) can always be represented as products of shifts and identites.

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 $k \to \infty$,

On the set of Fixed Points of the Parallel Symmetric Sand Pile Model [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2011
Sand Pile Models are discrete dynamical systems emphasizing the phenomenon of $\textit{Self-Organized Criticality}$. From a configuration composed of a finite number of stacked grains, we apply on every possible positions (in parallel) two grain moving ...

Error bounds in stochastic-geometric normal approximation [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
We provide normal approximation error bounds for sums of the form $\sum_x \xi_x$, indexed by the points $x$ of a Poisson process (not necessarily homogeneous) in the unit $d$-cube, with each term $\xi_x$ determined by the configuration of Poisson points ...

Point process stabilization methods and dimension estimation [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
We provide an overview of stabilization methods for point processes and apply these methods to deduce a central limit theorem for statistical estimators of dimension.

Rate of Escape of Random Walks on Regular Languages and Free Products by Amalgamation of Finite Groups [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
We consider random walks on the set of all words over a finite alphabet such that in each step only the last two letters of the current word may be modified and only one letter may be adjoined or deleted.

The height of random binary unlabelled trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
This extended abstract is dedicated to the analysis of the height of non-plane unlabelled rooted binary trees. The height of such a tree chosen uniformly among those of size $n$ is proved to have a limiting theta distribution, both in a central and local
