approximation theory
11Approximation algorithm — In computer science and operations research, approximation algorithms are algorithms used to find approximate solutions to optimization problems. Approximation algorithms are often associated with NP hard problems; since it is unlikely that there …
12Theory of cognitive development — The Theory of Cognitive Development (one of the most historically influential theories) was developed by Jean Piaget, a Swiss Philosopher (1896–1980). His genetic epistemological theory provided many central concepts in the field of developmental …
13Theory of equations — In mathematics, the theory of equations comprises a major part of traditional algebra. Topics include polynomials, algebraic equations, separation of roots including Sturm s theorem, approximation of roots, and the application of matrices and… …
14Constructive function theory — In mathematical analysis, constructive function theory is a field which studies the connection between the smoothness of a function and its degree of approximation[1][2]. It is closely related to approximation theory. The term was coined by… …

16Function approximation — The need for function approximations arises in many branches of applied mathematics, and computer science in particular. In general, a function approximation problem asks us to select a function among a well defined class that closely matches (… …
17Korovkin-Approximation — Bei der Korowkin Approximation handelt es sich um mathematische Konvergenzaussagen, in denen die Approximation von Funktionen durch gewisse Folgen von Funktionen untersucht wird. So werden in einer Anwendung (s.u.) stetige Funktionen durch… …
