On the column number and forbidden submatrices for $Δ$ -modular matrices

Joseph Paat, Ingo Stallknecht, Zach Walsh +1

An integer matrix $A$ is $Δ$ -modular if the determinant of each $rank (A) \times rank (A)$ submatrix of $A$ has absolute value at mo…

Improving proximity bounds using sparsity

Jon Lee, Joseph Paat, Ingo Stallknecht +1

We refer to the distance between optimal solutions of integer programs and their linear relaxations as proximity. In 2018, Eisenbrand and Weismantel proved that proximity is indepe…
