Asymptotic enumeration of lonesum matrices [PDF]

open access: yesAdvances in Applied Mathematics, 2021
We provide bivariate asymptotics for the poly-Bernoulli numbers, a combinatorial array that enumerates lonesum matrices, using the methods of Analytic Combinatorics in Several Variables (ACSV). For the diagonal asymptotic (i.e., for the special case of square lonesum matrices) we present an alternative proof based on Parseval's identity.

Lattice Enumeration with Discrete Pruning: Improvements, Cost Estimation and Optimal Parameters

open access: yesMathematics, 2023
Lattice enumeration is a linear-space algorithm for solving the shortest lattice vector problem (SVP). Extreme pruning is a practical technique for accelerating lattice enumeration, which has a mature theoretical analysis and practical implementation ...

A central limit theorem for numbers satisfying a class of triangular arrays associated with Hermite polynomials

open access: yesLietuvos Matematikos Rinkinys, 2021
The paper extends the investigations of limit theorems for numbers satisfying a class of triangular arrays. We obtain analytical expressions for the semiexponential generating function the numbers, associated with Hermite polynomials.

A bijection for nonorientable general maps [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
We give a different presentation of a recent bijection due to Chapuy and Dołe ̨ga for nonorientable bipartite quadrangulations and we extend it to the case of nonorientable general maps.

Central Limit Theorems for Combinatorial Numbers Associated with Laguerre Polynomials

open access: yesMathematics, 2022
In this paper, we study limit theorems for numbers satisfying a class of triangular arrays, which are defined by a bivariate linear recurrence with bivariate linear coefficients.

Asymptotic Enumeration of Hypergraphs by Degree Sequence [PDF]

open access: yesAdvances in Combinatorics, 2022
We prove an asymptotic formula for the number of k-uniform hypergraphs with a given degree sequence, for a wide range of parameters. In particular, we find a formula that is asymptotically equal to the number of d-regular k-uniform hypergraphs on n vertices provided that dn ≤ c(n/k) for a constant c > 0, and 3 ≤ k < n^c for any C < 1/9.

Accessible and Deterministic Automata: Enumeration and Boltzmann Samplers [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
We present a bijection between the set $\mathcal{A}_n$ of deterministic and accessible automata with $n$ states on a $k$-letters alphabet and some diagrams, which can themselves be represented as partitions of the set $[\![ 1..(kn+1) ]\!]$ into $n$ non ...
