Results and conjectures on simultaneous core partitions [PDF]
European journal of combinatorics (Print), 2013 An n-core partition is an integer partition whose Young diagram contains no hook lengths equal to n. We consider partitions that are simultaneously a-core and b-core for two relatively prime integers a and b.

Quantum crystals, Kagome lattice, and plane partitions fermion-boson duality [PDF]
, 2021 In this work we study quantum crystal melting in three space dimensions. Using an equivalent description in terms of dimers in a hexagonal lattice, we recast the crystal melting Hamiltonian as an occupancy problem in a Kagome lattice.

Theory of Computing Systems, 2016 We introduce a new concept, which we call partition expanders. The basic idea is to study quantitative properties of graphs in a slightly different way than it is in the standard definition of expanders. While in the definition of expanders it is required that the number of edges between any pair of sufficiently large sets is close to the expected ...

A simple proof of Pitman–Yor’s Chinese restaurant process from its stick-breaking representation
Dependence Modeling, 2019 For a long time, the Dirichlet process has been the gold standard discrete random measure in Bayesian nonparametrics. The Pitman-Yor process provides a simple and mathematically tractable generalization, allowing for a very flexible control of the ...

Top Coefficients of the Denumerant [PDF]
Discrete Mathematics & Theoretical Computer Science, 2013 For a given sequence $\alpha = [\alpha_1,\alpha_2,\ldots , \alpha_N, \alpha_{N+1}]$ of $N+1$ positive integers, we consider the combinatorial function $E(\alpha)(t)$ that counts the nonnegative integer solutions of the equation $\alpha_1x_1+\alpha_2 x_2+

A worldwide coastal analysis of the climate wave systems
Frontiers in Marine ScienceWind generated waves of a sea state are generally the result of the superposition of wind sea and swells, making the frequency-direction wave energy distribution crucial for comprehending this behavior.

A q-Series Congruence Inspired by Andrews and Ramanujan
Axioms, 2023 For each s∈{1,3,5}, we consider Rs(n) to be the number of the partitions of n into parts not congruent to 0, ±s(mod12). In recent years, some relations for computing the value of R3(n) were studied.

Partition Statistics for Cubic Partition Pairs [PDF]
The Electronic Journal of Combinatorics, 2011 In this brief note, we give two partition statistics which explain the following partition congruences: \begin{align*} b(5n+4) &\equiv 0 \pmod{5}, \\ b(7n+a) &\equiv 0 \pmod{7}, \text{if $a=2$, $3$, $4$, or $6$}. \end{align*} Here, $b(n)$ is the number of $4$-color partitions of $n$ with colors $r$, $y$, $o$, and $b$ subject to the ...
