In mathematics, the Hermite constant γn for integers n > 0, named after Charles Hermite, is defined as follows. Given a lattice L in Euclidean space Rn, let λ1(L) denote the least length of a nonzero element of L. Then
is the maximum of λ1(L) over all lattices L of unit covolume, i.e. vol(Rn/L) = 1.
