Products of parametric extensions: refined estimates

Journal of Numerical Analysis and Approximation Theory
We present point wise estimates on approximation by bounded linear operators of real-valued continuous functions defined on the cartesian product of d compact intervals. The main purpose is to provide a unified theory to deal with pointwise estimates on

Constructive approximation theory [PDF]

, 2007
We consider the fundamental Theorem of Approximation Theory from a constructive viewpoint, revealing that the theorem itself is fundamentally non-constructive. We subsequently present a development of a constructive alternative to the Fundamental Theorem,

Bernstein-Walsh theory associated to convex bodies and applications to multivariate approximation theory

, 2017
We prove a version of the Bernstein-Walsh theorem on uniform polynomial approximation of holomorphic functions on compact sets in several complex variables. Here we consider subclasses of the full polynomial space associated to a convex body P.

Approximation Theory and Elementary Submodels [PDF]

\emph{Approximation Theory} uses nicely-behaved subcategories to understand entire categories, just as projective modules are used to approximate arbitrary modules in classical homological algebra. We use set-theoretic \emph{elementary submodel arguments}

Exact constants in approximation theory

, 1991
This book is intended as a self-contained introduction for non-specialists, or as a reference work for experts, to the particular area of approximation theory that is concerned with exact constants.
