Best Constants between Equivalent Norms in Lorentz Sequence Spaces

We find the best constants in inequalities relating the standard norm, the dual norm, and the norm ∥x∥(p,s):=inf⁡{∑k∥x(k)∥p,s}, where the infimum is taken over all finite representations x=∑kx(k) in the classical Lorentz sequence spaces. A crucial point in this analysis is the concept of level seque...
