Given an n × n matrix A, define the n! × n! matrix Ã, with rows and columns indexed by the permutation group Sn, with (σ, τ) entry Πni=1aτ(i), σ(i). It is shown that if A is positive semidefinite, then det A is the smallest eigenvalue of Ã; it is conjectured that per A is the largest eigenvalue of Ã, and the conjecture proved for n⩽3. Several known and some unknown inequalities are derived as consequences.
In the present article we extend the best Nike Free Run 5.0 Uk constant approximant operator from Lorentz spaces Γp,wΓp,w to Γp−1,wΓp−1,w for any 1<p<∞1<p<∞ and w≥0w≥0 a locally integrable weight function, and from Γ1,wΓ1,w to the space of all measurable functions L0L0. Then we establish several properties of the extended best constant approximant operator and finally, we prove a generalized version of the
Lebesgue Differentiation Theorem in L0L0.

It is shown that the Nike Roshe Trainers Navy
minimal set of coupled equations must include all the two-cluster channels in order to satisfy the unitarity condition.
