Forbidding $r$ -extension of $C_{4}$ -- a counterexample of the Anstee-Sali conjecture

Richard P. Anstee, Attila Sali, Pei Wu

In this note we prove $forb (n, 1_{r - 2} \times C_{4}) = Θ (n^{r - 1/2})$ , thus providing a series of counterexamples of a 2005 conjecture of the first two authors. Here $\m…

Exact Bounds for Forbidden Configurations and the Extremal Matrices

Richard P. Anstee, Oakley Edens, Arvin Sahami +2

Let $F$ be a $k \times ℓ$ (0,1)-matrix. A matrix is simple if it is a (0,1)-matrix with no repeated columns. A (0,1)-matrix $A$ is said to have a $F$ as a configuration if there…
