A Geometric Characterization of Maximal Unrefinable Partitions via the Keith-Nath Transformation and Young Diagrams

Riccardo Aragona, Roberto Civino, Lorenzo Campioni

We investigate the combinatorial structure of unrefinable partitions through their correspondence with numerical sets and Young diagrams. Building on the bijection introduced by Ke…

A definitely periodic chain in the integral Lie ring of partitions

Riccardo Aragona, Roberto Civino, Norberto Gavioli

Given an integer , we introduce the integral Lie ring of partitions with bounded maximal part, whose elements are in one-to-one correspondence to integer partitions with parts i…

The number of maximal unrefinable partitions

Riccardo Aragona, Lorenzo Campioni, Roberto Civino

This paper completes the classification of maximal unrefinable partitions, extending a previous work of Aragona et al. devoted only to the case of triangular numbers. We show that…

Verification and generation of unrefinable partitions

Riccardo Aragona, Lorenzo Campioni, Roberto Civino +1

Unrefinable partitions are a subset of partitions into distinct parts which satisfy an additional unrefinability property. More precisely, being an unrefinable partition means that…

On the maximal part in unrefinable partitions of triangular numbers

Riccardo Aragona, Lorenzo Campioni, Roberto Civino +1

A partition into distinct parts is refinable if one of its parts can be replaced by two different integers which do not belong to the partition and whose sum is , and it is…

Unrefinable partitions into distinct parts in a normalizer chain

Riccardo Aragona, Roberto Civino, Norberto Gavioli +1

In a recent paper on a study of the Sylow 2-subgroups of the symmetric group with 2^n elements it has been show that the growth of the first (n-2) consecutive indices of a certain…
