An arithmetic proof of John's ellipsoid theorem
Peter M. Gruber, Franz E. Schuster
Using an idea of Voronoi in the geometric theory of positive definite quadratic forms, we give a transparent proof of John's characterization of the unique ellipsoid of maximum vol…
An Optimal Lower Bound for the Frobenius Problem
Iskander Aliev, Peter Gruber
Given positive integers with , let denote the largest natural number which is not a positive integer combination of …
Best Simultaneous Diophantine Approximations under a Constraint on the Denominator
Iskander Aliev, Peter Gruber
We investigate the problem of best simultaneous Diophantine approximation under a constraint on the denominator, as proposed by Jurkat. New lower estimates for optimal approximatio…
Lattice Points in Large Borel Sets and Successive Minima
Iskander Aliev, Peter Gruber
Let be a Borel set in with volume . It is shown that almost all lattices in contain infinitely many pairwise disjoint -tuple…
