Title
On a completion problem for Latin arrays
Abstract
An n x n (partial) Latin array L is an array in which no symbol appears more than once in any row or column; this differs from a (partial) Latin square in that L may have up to n(2) distinct symbols present. We say L is k-completable if there exists a partition of the symbols of L into k parts so that the corresponding induced subarrays are each completable partial Latin squares. In 2015 Kuhl and Schroeder demonstrated the existence of n x n partial Latin arrays which are not k-completable for each k < n, and in this paper, we show that all n x n partial Latin arrays are n-completable. This addresses a conjecture by Kuhl and Schroeder and also confirms a special case of a conjecture by Haggkvist.
