Large expanders in high genus unicellular maps [PDF]

open access: yes, 2022
We study large uniform random maps with one face whose genus grows linearly with the number of edges. They can be seen as a model of discrete hyperbolic geometry.

Pattern Avoidance for Random Permutations [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2018
Using techniques from Poisson approximation, we prove explicit error bounds on the number of permutations that avoid any pattern. Most generally, we bound the total variation distance between the joint distribution of pattern occurrences and a ...

The Largest Component in Critical Random Intersection Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2018
In this paper, through the coupling and martingale method, we prove the order of the largest component in some critical random intersection graphs is n23$n^{{2 \over 3}}$ with high probability and the width of scaling window around the critical ...

An Overlapping theorem with applications [PDF]

open access: yes, 2007
12 páginas.-- 2000 Mathematics Subject Classification. 60C05.We establish a general and optimal lower bound for the complete sum of the probabilities of k-intersections of n events.

Variance and Covariance of Several Simultaneous Outputs of a Markov Chain [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2016
The partial sum of the states of a Markov chain or more generally a Markov source is asymptotically normally distributed under suitable conditions. One of these conditions is that the variance is unbounded.

Characterization of stationary probability measures for Variable Length Markov Chains [PDF]

open access: yes, 2018
By introducing a key combinatorial structure for words produced by a Variable Length Markov Chain (VLMC), the longest internal suffix, precise characterizations of existence and uniqueness of a stationary probability measure for a VLMC chain are given ...

A PROOF OF ANDREWS’ CONJECTURE ON PARTITIONS WITH NO SHORT SEQUENCES

open access: yesForum of Mathematics, Sigma, 2019
Our main result establishes Andrews’ conjecture for the asymptotic of the generating function for the number of integer partitions of $n$ without $k$ consecutive parts.

Extended Fibonacci numbers and polynomials with probability applications

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 50, Page 2681-2693, 2004., 2004
The extended Fibonacci sequence of numbers and polynomials is introduced and studied. The generating function, recurrence relations, an expansion in terms of multinomial coefficients, and several properties of the extended Fibonacci numbers and polynomials are obtained.

FINITELY DEPENDENT COLORING

open access: yesForum of Mathematics, Pi, 2016
We prove that proper coloring distinguishes between block factors and finitely dependent stationary processes. A stochastic process is finitely dependent if variables at sufficiently well-separated locations are independent; it is a block factor if it ...

Culminating paths [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2007
Let a and b be two positive integers. A culminating path is a path of Z^2 that starts from (0,0), consists of steps (1,a) and (1,-b), stays above the x-axis and ends at the highest ordinate it ever reaches.
