Approximation property — In mathematics, a Banach space is said to have the approximation property (AP in short), if every compact operator is a limit of finite rank operators. The converse is always true.Every Hilbert space has this property. There are, however, Banach… … Wikipedia
Approximation der Eins — Eine Approximation der Eins ist ein Begriff aus der mathematischen Theorie der Banachalgebren. Viele für Anwendungen wichtige Banachalgebren haben kein Einselement. Eine Adjunktion eines Einselement wäre in der Regel ein unnatürliches Vorgehen.… … Deutsch Wikipedia
Born-Oppenheimer approximation — In quantum chemistry, the computation of the energy and wavefunction of an average size molecule is a formidable task that is alleviated by the Born Oppenheimer (BO) approximation. For instance the benzene molecule consists of 12 nuclei and 42… … Wikipedia
Sobel operator — The Sobel operator is used in image processing, particularly within edge detection algorithms. Technically, it is a discrete differentiation operator, computing an approximation of the gradient of the image intensity function. At each point in… … Wikipedia
Rotating wave approximation — The rotating wave approximation is an approximation used in atom optics and magnetic resonance. In this approximation, terms in a Hamiltonian which oscillate rapidly are neglected. This is a valid approximation when the applied electromagnetic… … Wikipedia
Korovkin-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… … Deutsch Wikipedia
Compact operator — In functional analysis, a branch of mathematics, a compact operator is a linear operator L from a Banach space X to another Banach space Y, such that the image under L of any bounded subset of X is a relatively compact subset of Y. Such an… … Wikipedia

Born-Oppenheimer-Approximation — Die Born Oppenheimer Näherung oder Born Oppenheimer Approximation oder adiabatische Näherung ist eine Methode zur Lösung der Schrödingergleichung für ein System mit mehreren schweren und wenigstens einem leichten Teilchen. Dieses Problem tritt… … Deutsch Wikipedia
Slowly varying envelope approximation — In physics, the slowly varying envelope approximation (SVEA) is the assumption that the envelope of a forward travelling wave pulse varies slowly in time and space compared to a period or wavelength. This requires the spectrum of the signal to be … Wikipedia
Compact operator on Hilbert space — In functional analysis, compact operators on Hilbert spaces are a direct extension of matrices: in the Hilbert spaces, they are precisely the closure of finite rank operators in the uniform operator topology. As such, results from matrix theory… … Wikipedia
