Geometry of numbers
Geometry of numbers is the part of
The geometry of numbers has a close relationship with other fields of mathematics, especially functional analysis and Diophantine approximation, the problem of finding rational numbers that approximate an irrational quantity.[2]
Minkowski's results
Suppose that is a lattice in -dimensional Euclidean space and is a convex centrally symmetric body. Minkowski's theorem, sometimes called Minkowski's first theorem, states that if , then contains a nonzero vector in .
The successive minimum is defined to be the
Later research in the geometry of numbers
In 1930–1960 research on the geometry of numbers was conducted by many
Subspace theorem of W. M. Schmidt
In the geometry of numbers, the
lie in a finite number of proper subspaces of Qn.
Influence on functional analysis
Minkowski's geometry of numbers had a profound influence on
Researchers continue to study generalizations to
