Mahmoodian (Sharif University of Technology | Abstract: | A critical set in an n x n array is a set C of given entries, such that there exists a unique extension of C to an n x n Latin square and no proper subset of C has this property. The cardinality of the largest critical set in any Latin square of order n is denoted by lcs(n). In 1978 Curran and van Rees proved that lcs(n) <= n^2 - n. Here we show that lcs(n) <= n^2-3n+3. | Source: | arXiv, math.CO/0107159 | Services: | Forum | Review | PDF | Favorites |
