POLARIZATION AND UNCONDITIONAL CONSTANTS OF 𝓟(2d*(1,ω)2)

Extension Constants of Unconditional Two-Dimensional Operators

It is shown that the (absolute) extension constant e(T) of an operator T such that TG, = h,v,, k = 1,2, for some unconditional basis (ol, r;,> of a two-dimensional real normed space is less than or equal to (1~~1 + IA,1 + 2 AT IA,h,J + Ai )/3. In fact, it is demonstrated that e(T) is attained by exactly one unconditional two-dimensional space (up to an isometry).

Lower estimates of random unconditional constants of Walsh-Paley martingales with values in Banach spaces

for all n = 1, 2, ... and all martingales {Mk}0 ⊂ L X p with values in X . It turns out that this definition is equivalent to the modified one if we replace ”for all 1 < p < ∞” by ”for some 1 < p < ∞”, and ”for all martingales” by ”for all Walsh-Paley-martingales” (see [3] for a survey). Motivated by these definitions we investigate Banach spaces X by means of the sequences {RUMDn(X)}n=1 wherea...
