Fully degenerate poly-Bernoulli numbers and polynomials

open access: yesOpen Mathematics, 2016
In this paper, we introduce the new fully degenerate poly-Bernoulli numbers and polynomials and inverstigate some properties of these polynomials and numbers.

Consequences of a sextuple‐product identity

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 10, Issue 3, Page 545-549, 1987., 1987
A sextuple‐product identity, which essentially results from squaring the classical Gauss‐Jacobi triple‐product identity, is used to derive two trigonometrical identities. Several special cases of these identities are then presented and discussed.

Classical pattern distributions in $\mathcal{S}_{n}(132)$ and $\mathcal{S}_{n}(123)$ [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2019
Classical pattern avoidance and occurrence are well studied in the symmetric group $\mathcal{S}_{n}$. In this paper, we provide explicit recurrence relations to the generating functions counting the number of classical pattern occurrence in the set of ...

Consecutive Patterns in Inversion Sequences [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2019
An inversion sequence of length $n$ is an integer sequence $e=e_{1}e_{2}\dots e_{n}$ such that $0\leq e_{i}

Topological recursion for fully simple maps from ciliated maps [PDF]

open access: yes
We solve a conjecture from the first and third authors that claims that fully simple maps, which are maps with non self-intersecting disjoint boundaries, satisfy topological recursion for the exchanged spectral curve \((y, x)\), making use of the ...

Some formulas for the restricted r-Lah numbers [PDF]

open access: yes, 2018
The r-Lah numbers, which we denote here by `(r)(n, k), enumerate partitions of an (n+r)-element set into k+r contents-ordered blocks in which the smallest r elements belong to distinct blocks. In this paper, we consider a restricted version `(r) m (n,

The graham–knuth–patashnik recurrence: symmetries and continued fractions

open access: yes, 2022
72 pags. -- Mathematics Subject Classifications: 05A10 (Primary); 05A15, 05A19, 30B70 (Secondary)We study the triangular array defined by the Graham–Knuth–Patashnik recurrence T (n, k) = (αn + βk + γ) T (n − 1, k) + (αn + βk + γ ) T (n − 1, k − 1) with ...

A Pipe Dream Perspective on Totally Symmetric Self-Complementary Plane Partitions

open access: yesForum of Mathematics, Sigma
We characterize totally symmetric self-complementary plane partitions (TSSCPP) as bounded compatible sequences satisfying a Yamanouchi-like condition. As such, they are in bijection with certain pipe dreams.

The 26 Wilf-equivalence classes of length five quasi-consecutive patterns [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2018
We present two families of Wilf-equivalences for consecutive and quasi-consecutive vincular patterns. These give new proofs of the classification of consecutive patterns of length $4$ and $5$.

and [PDF]

open access: yes, 2009
. We study the descent distribution over the set of centrosymmetric permutations that avoid a pattern of length 3. In the most puzzling case, namely, τ = 123 and n even, our main tool is a bijection that associates a Dyck pre x of length 2n to every ...
