Hlawka
Hlawka refers to a concept in mathematics, specifically in functional analysis and convex geometry. It is named after the Austrian mathematician Edmund Hlawka. The Hlawka inequality is a fundamental result concerning the norm of vectors in a normed vector space.
In a normed vector space, the Hlawka inequality provides a relationship between the norm of the sum
This inequality is a generalization of Ptolemy's inequality in Euclidean spaces and has significant implications for
