Geometry of Numbers is an area of mathematics pioneered by Hermann Minkowski at the end of the 19th century. He achieved stunning success introducing a novel geometric framework into the study of algebraic numbers, prompting mathematicians of later generations to compare his work to "the story of Saul, who set out to look for his father's asses and discovered a Kingdom" (J. V. Armitage). In this talk, we will look at some contemporary variations of Minkowski's classical results that will take us on a journey from linear algebra and convex analysis to algebraic number theory and arithmetic geometry. This is joint work with P. Guerzhoy and S. Kuehnlein.
