Abstract
A 0-1 matrix contains a 0-1 matrix pattern if we can obtain from by deleting rows and/or columns and turning arbitrary 1-entries into 0s. The saturation function for a 0-1 matrix pattern indicates the minimum number of 1s in a 0-1 matrix that does not contain , but changing any 0-entry into a 1-entry creates an occurrence of . Fulek and Keszegh recently showed that the saturation function is either bounded or in . Building on their results, we find a large class of patterns with bounded saturation function, including both infinitely many permutation matrices and infinitely many non-permutation matrices.
