On a problem involving unit fractions
Stefan Steinerberger
Erdős and Graham proposed to determine the number of subsets with and asked, among other things, whether that numb…
A Note on Approximate Hadamard Matrices
Stefan Steinerberger
A Hadamard matrix is a scaled orthogonal matrix with entries. Such matrices exist in certain dimensions: the Hadamard conjecture is that such a matrix always exists when $n…
Graph curvature via resistance distance
Karel Devriendt, Andrea Ottolini, Stefan Steinerberger
Let be a finite, combinatorial graph. We define a notion of curvature on the vertices via the inverse of the resistance distance matrix. We prove that this notion of…
On Combinatorial Properties of Greedy Wasserstein Minimization
Stefan Steinerberger
We discuss a phenomenon where Optimal Transport leads to a remarkable amount of combinatorial regularity. Consider infinite sequences in constructed…
