On maximal premature partial Latin squares
نویسنده
چکیده
A partial Latin square is premature if it has no completion, but it admits a completion after removing any of its symbols. This type of partial Latin square has been introduced by Brankovic, Honik, Miller and Rosa [Ars Combinatoria, to appear] where the authors showed that the number of empty cells in an n x n premature latin square is at least 371 4. vVe improve this lower bound to 7n/2 0(71,).

The completion of partial Latin squares
In recent times there has been some interest in studying partial latin squares which have no completions or precisely one completion, and which are critical with respect to this property. Such squares are called, respectively, premature partial latin squares and critical sets. There has also been interest in related maximal partial latin squares. This paper will explore the connection between t...
متن کاملPremature partial latin squares
We introduce the notion of premature partial latin squares; these cannot be completed, but if any of the entries is deleted, a completion is possible. We study their spectrum, i.e., the set of integers t such that there exists a premature partial latin square of order n with exactly t nonempty cells.
متن کاملSteiner Trades That Give Rise to Completely Decomposable Latin Interchanges
In this paper we focus on the representation of Steiner trades of volume less than or equal to nine and identify those for which the associated partial latin square can be decomposed into six disjoint latin interchanges. 1 Background information In any combinatorial configuration it is possible to identify a subset which uniquely determines the structure of the configuration and in some cases i...
متن کاملOn the Length of a Partial Independent Transversal in a Matroidal Latin Square
We suggest and explore a matroidal version of the Brualdi Ryser conjecture about Latin squares. We prove that any n × n matrix, whose rows and Columns are bases of a matroid, has an independent partial transversal of length d2n/3e. We show that for any n, there exists such a matrix with a maximal independent partial transversal of length at most n− 1.
متن کاملThe set of autotopisms of partial Latin squares
Symmetries of a partial Latin square are primarily determined by its autotopism group. Analogously to the case of Latin squares, given an isotopism Θ, the cardinality of the set PLSΘ of partial Latin squares which are invariant under Θ only depends on the conjugacy class of the latter, or, equivalently, on its cycle structure. In the current paper, the cycle structures of the set of autotopisms...
