Exact ,-Widths of Integral Operators,. is a nondegenerate totally positive kernel. (Such kernels were defined in Section 5 of Chapter IV and are redefined in Section 2.) We prove that all three .-widths considered are equal (the common value depending on . and .) and that there exists a set of . distinct points in {.}. in (0,1) for whi

Asymptotic Estimates for ,-Widths of Sobolev Spaces,r of the values .(.;.), .(.; .) and ..(.;.) for .,., ∈ as . grows. It is only recently that this problem has been solved for all ., . ∈ (and almost all .). We first state the major result proven in this chapter.

-Widths of Analytic Functions,In this chapter we consider .-widths of various classes of analytic functions. Our concern is with exact .-widths and the identification of optimal subspaces. Asymptotic estimates are relegated to the “Notes and References” at the end of the chapter.
