摘要:
We provide a survey of the contributors of Des Evans dealing with operators T of the form T F(x) = v(x)integral(x)(a) u(t)f(t) dt acting between Lehesgue spaces, and also report on new results concerning the Bernstein widths and Kolmogorov numbers of T. (c) 2006 Elsevier B.V. All rights reserved.
