On the Essential and ω-Essential Norms of a Linear Operator in Weighted Sequence Spaces

UNIVERSITY NEWS. NORTH-CAUCASIAN REGION. NATURAL SCIENCES SERIES
The study of essential and ω-essential norms of linear continuous operators in quasi-Banach weighted sequence spaces l^p ("w" ) aims to generalize classical results to the case of spaces with 0<p<1. Previously, similar problems were addressed for Hilbert (p=2) and Banach (p>1) spaces.
