operators on L ( L p ) and ` p - strictly singular operators

A classification of weakly compact multiplication operators on L(Lp), 1 < p < ∞, is given. This answers a question raised by Saksman and Tylli in 1992. The classification involves the concept of `p-strictly singular operators, and we also investigate the structure of general `p-strictly singular operators on Lp . The main result is that if an operator T on Lp , 1 < p < 2, is `p-strictly singula...

Inapproximability of Matrix $p \rightarrow q$ Norms

This problem generalizes the spectral norm of a matrix (p = q = 2) and the Grothendieck problem (p = ∞, q = 1), and has been widely studied in various regimes. When p ≥ q, the problem exhibits a dichotomy: constant factor approximation algorithms are known if 2 ∈ [q, p], and the problem is hard to approximate within almost polynomial factors when 2 / ∈ [q, p]. The regime when p < q, known as hy...

KADEC-KLEE PROPERTIES FOR L(`p, `q)

It is proved that L(`p, `q) has the KK property if and only if it has the UKK property if and only if 1 < q < 2 < p < ∞. It is also proved that L(c0, `1) has the UKK property and that L(c0, `q) can be renormed to have the weak-star UKK property if (and only if) 1 ≤ q < 2. In all other cases L(`p, `q) has no equivalent UKK norm. Finally, it is proved that none of these spaces is either strictly ...

The Purely Leptonic Decays D + → μ + ν and D + s → l + ν at CLEO

(1) where GF is the Fermi constant, MD+ is theD + mass, ml the final state charged-lepton mass, and Vcd is a CKM matrix element, taken equal to Vus. Thus, in the SM measurement of purely leptonic decays allow a determination the decay constant, fD+ of the D + meson and similarly fDs of the D + s meson. Meson decay constants in the B system are used to translate measurements of BB̄ mixing to CKMm...
