Linear-size $ℓ_{1}$ sparsifiers

Victor Reis, Thomas Rothvoss

We prove that for any matrix $A \in R^{m \times n}$ and any $ε > 0$ there is a diagonal matrix $D \in R_{\geq 0}^{m \times m}$ with at most $O(\frac{n}{…

Optimal Vector Balancing for Zonotopes

Victor Reis

A zonotope is a linear image of the cube $[- 1, 1]^{m}$ for some $m \in N$ . We show that there is a universal constant $C$ such that, for every zonotope $Z\subset \mathbb{R}^d…

The Subspace Flatness Conjecture and Faster Integer Programming

Victor Reis, Thomas Rothvoss

In a seminal paper, Kannan and LovÃ¡sz (1988) considered a quantity $I^¼_{K L} (I^, K)$ which denotes the best volume-based lower bound on the covering radius $I^¼ (I^, K)$ of a convex bo…

Weighted Chairman Assignment and Flow-Time Scheduling

Siyue Liu, Victor Reis

Given positive integers $m, n$ , a fractional assignment $x \in [0, 1]^{m \times n}$ and weights $d \in R_{> 0}^{n}$ , we show that there exists an assignment $y \in \{0,1\}^{m…
