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…

Forbidden Configurations and Boundary Cases

Richard P. Anstee, Oakley Edens, Arvin Sahami +1

Let $F$ be a $k \times ℓ$ (0,1)-matrix. Define a (0,1)-matrix $A$ to have a $F$ as a \emph{configuration} if there is a submatrix of $A$ which is a row and column permutation of…
