Contribution & Novelties
The talk presents a new result improving the gap for the Subspace Flatness Conjecture from polynomial to polylogarithmic, which directly impacts the flatness constant and algorithms for integer programming. The proof combines the reverse Minkowski theorem, stable lattices, and L-positioning, offering new insights into the interaction between geometry and computation.
