On unconditionality of fractional Rademacher chaos in symmetric spaces
S. V. Astashkin, K. V. Lykov
We study density estimates of an index set , under which unconditionality (or even a weaker property of the random unconditional divergence) of the corresponding Radem…

Majorization revisited: Comparison of norms in interpolation scales
Sergey V. Astashkin, Konstantin V. Lykov, Mario Milman
We reformulate, modify and extend a comparison criteria of norms obtained by Nazarov-Podkorytov and place it in the general setting of interpolation theory and majorization…

Limiting interpolation spaces via extrapolation
Sergey V. Astashkin, Konstantin V. Lykov, Mario Milman
We give a complete characterization of limiting interpolation spa\-ces for the real method of interpolation using extrapolation theory. For this purpose the usual tools (e.g., Boyd…
