Antichains among Divisor Sums of Divisors

Felix Huber

For a positive integer $n$ , let $S (n) = {σ (d) : d ∣ n}$ be ordered by divisibility, and let $a (n)$ be its width. We study how much of the divisor lattice of $n$ survives under the…

Extremal Least Common Multiples in Rows of Pascal's Triangle

Felix Huber

For $r \geq 0$ , let $P_{r} = {(0 r), (1 r), \dots, (⌊ r /2 ⌋ r)}$ be the set of distinct entries in row $r$ of Pascal's triangle. We study the le…

Large Sidon Subsets and Pair-Sum Multiplicities of Distinct Multinomial Coefficients

Felix Huber

For a positive integer $n$ , let $M_{n}$ be the set of distinct multinomial coefficient values $n! / (p_{1}! \dots p_{t}!)$ , where $(p_{1}, \dots, p_{t})$ ranges over the integer parti…

Iterated Distinct Absolute Differences of Integer Compositions

Felix Huber

Starting from an integer composition, form its consecutive absolute differences, provided that they are nonzero and pairwise distinct, and then permute these differences arbitraril…
