%C A132116 Dolbeault et al. Abstract, where this is referred to as "the semiclassical 
               constant" following remark 2, p. 2: "Following Eden and Foias we 
               obtain a matrix version of a generalised Sobolev inequality in one-dimension. 
               This allow us to improve on the known estimates of best constants 
               in Lieb-Thirring inequalities for the sum of the negative eigenvalues 
               for multi-dimensional Schroedinger operators."
