Notes on ${a, b, c}$ -Modular Matrices

Christoph Glanzer, Ingo Stallknecht, Robert Weismantel

Let $A \in Z^{m \times n}$ be an integral matrix and $a$ , $b$ , $c \in Z$ satisfy $a \geq b \geq c \geq 0$ . The question is to recognize whether $A$ is ${a, b, c}$ …

Polynomial upper bounds on the number of differing columns of $Δ$ -modular integer programs

Jon Lee, Joseph Paat, Ingo Stallknecht +1

We study integer-valued matrices with bounded determinants. Such matrices appear in the theory of integer programs (IP) with bounded determinants. For example, Artmann et al. showe…
