Note On Extreme Forms
Published online by Cambridge University Press: 20 November 2018
Extract
Let ƒ(x1, … , xn) = Σaijxixj be a positive definite quadratic form of determinant D = |aij|, and let M be the minimum of f for integral x1, … , xn not all zero. The form ƒ is said to be extreme if the ratio Mn/D does not increase when the coefficients aij of f suffer any sufficiently small variation.
