External Characterization of I-Favorable Spaces
http://hdl.handle.net/10525/2689
Title: External Characterization of I-Favorable Spaces<br/><br/>Authors: Valov, Vesko<br/><br/>Abstract: We provide both a spectral and an internal characterizations of arbitrary !-favorable spaces with respect to co-zero sets. As a corollary we establish that any product of compact !-favorable spaces with respect to co-zero sets is also !-favorable with respect to co-zero sets. We also prove that every C* -embedded !-favorable with respect to co-zero sets subspace of an extremally disconnected space is extremally disconnected.<br/><br/>Description: 1991 AMS Math. Subj.

Title: On the Approximation by Convolution Operators in Homogeneous Banach Spaces of Periodic Functions<br/><br/>Authors: Draganov, Borislav R.<br/><br/>Abstract: The paper is concerned with establishing direct estimates for convolution operators on homogeneous Banach spaces of periodic functions by means of appropriately defined Kfunctional. The differential operator in the K-functional is defined by means of strong limit and described explicitly in terms of its Fourier coefficients. The description is simple and independent of the homogeneous Banach space. Saturation of such operators is also considered.<br/><br/>Description: AMS Subject Classification 2010: 41A25, 41A27, 41A35, 41A36, 41A40, 42Al6, 42A85.Weighted Approximation by a Class of Bernstein-Type Operators
