Correlations in totally symmetric self‐complementary plane partitions

open access: yesTransactions of the London Mathematical Society, 2021
Totally symmetric self‐complementary plane partitions (TSSCPPs) are boxed plane partitions with the maximum possible symmetry. We use the well‐known representation of TSSCPPs as a dimer model on a honeycomb graph enclosed in 1/12 of a hexagon with free ...

On Graham partitions twisted by the Legendre symbol

open access: yesOpen Mathematics, 2023
We investigate when there is a partition of a positive integer nn, n=f(λ1)+f(λ2)+⋯+f(λℓ),n=f\left({\lambda }_{1})+f\left({\lambda }_{2})+\cdots +f\left({\lambda }_{\ell }), satisfying that 1=χp(λ1)λ1+χp(λ2)λ2+⋯+χp(λℓ)λℓ,1=\frac{{\chi }_{p}\left({\lambda }

MacMahon’s statistics on higher-dimensional partitions

open access: yesForum of Mathematics, Sigma, 2023
We study some combinatorial properties of higher-dimensional partitions which generalize plane partitions. We present a natural bijection between d-dimensional partitions and d-dimensional arrays of nonnegative integers.

Dynamics of plane partitions: Proof of the Cameron–Fon-Der-Flaass conjecture

open access: yesForum of Mathematics, Sigma, 2020
One of the oldest outstanding problems in dynamical algebraic combinatorics is the following conjecture of P. Cameron and D. Fon-Der-Flaass (1995): consider a plane partition P in an $a \times b \times c$ box ${\sf B}$ . Let $\Psi (P)$

Parity results for broken 11-diamond partitions

open access: yesOpen Mathematics, 2019
Recently, Dai proved new infinite families of congruences modulo 2 for broken 11-diamond partition functions by using Hecke operators. In this note, we establish new parity results for broken 11-diamond partition functions.

Some congruences for 3-component multipartitions

open access: yesOpen Mathematics, 2016
Let p3(n) denote the number of 3-component multipartitions of n. Recently, using a 3-dissection formula for the generating function of p3(n), Baruah and Ojah proved that for n ≥ 0, p3(9n + 5) ≡ 0 (mod 33) and p3 (9n + 8) ≡ 0 (mod 34).

On Partitions and Arf Semigroups

open access: yesOpen Mathematics, 2019
In this study we examine some combinatorial properties of the Arf semigroup. In previous work, the author and Karakaş, Gümüşbaş defined an Arf partition of a positive integer n. Here, we continue this work and give new results on Arf partitions.

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.

Arithmetic properties for Andrews’ (48,6)- and (48,18)-singular overpartitions

open access: yesOpen Mathematics, 2019
Singular overpartition functions were defined by Andrews. Let Ck,i(n) denote the number of (k, i)-singular overpartitions of n, which counts the number of overpartitions of n in which no part is divisible by k and only parts ±i (mod k) may be overlined ...

A Note on Graph Burning of Path Forests [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
Graph burning is a natural discrete graph algorithm inspired by the spread of social contagion. Despite its simplicity, some open problems remain steadfastly unsolved, notably the burning number conjecture, which says that every connected graph of order $
