21 p, 353.7 KB Blei's inequality and coordinatewise multiple summing operators / Popa, Dumitru ; Sinnamon, Gord
Two inequalities resembling the multilinear Hölder inequality for mixednorm Lebesgue spaces are proved. When specialized to single-function inequalities they include a pair of inequalities due to Blei and a recent extension of Blei's inequality. [...]

27 p, 224.2 KB The Fourier transform in weighted Lorentz spaces / Sinnamon, Gord
Necessary conditions and sufficient conditions on weights u and w are given for the Fourier transform F to be bounded as a map between the Lorentz spaces Γq(w) and Λp(u). This may be viewed as a weighted extension of a result of Jodeit and Torchinsky on operators of type (1, ∞) and (2, 2). [...]

27 p, 220.7 KB Embeddings of concave functions and duals of Lorentz spaces / Sinnamon, Gord
A simple expression is presented that is equivalent to the norm of the Lpv --> Lqu embedding of the cone of quasi-concave functions in the case 0 < q < p < [infininy]. The result is extended to more general cones and the case q = 1 is used to prove a reduction principle which shows that questions of boundedness of operators on these cones may be reduced to the boundedness of related operators on whole spaces.

24 p, 203.5 KB The Level function in rearrangement invariant spaces / Sinnamon, Gord
An exact expression for the down norm is given in terms of the level function on all rearrangement invariant spaces and a useful approximate expression is given for the down norm on all rearrangement invariant spaces whose upper Boyd index is not one.
