(1997)We use Humbert's reduction theory to introduce an obstruction for the unimodularity of minimal vectors of positive definite quadratic forms over totally real number fields. Using this obstruction we obtain an inequality ...

(2003)Let F be a field of characteristic 2. Let ΩFn be the F-space of absolute differential forms over F. There is a homomorphism ℘: ΩFn → ΩFn/dΩFn-1 given by ℘ (x dx1/x1 ∧ ⋯ ∧ dxn/xn) = (x2-x)dx1/x1 ∧ ⋯ ∧ dxn/xn mod dΩFn-1. Let ...
