• FLUCTUATION EXPANSION FOR A UNIVARIATE FUNCTION’S MATRIXREPRESENTATION
METIN DEMIRALP (pp. 176-193)
• #### Abstract

The matrix representation of a univariate function operator is considered. A rapidlyconverging scheme is constructed via a fluctuation operator projecting to the complement ofthe space spanned by a finite number of bases. We give only first two terms although theconstruction of whole approximation is possible.

#### Keywords

Hilbert spaces, matrix representation, fluctuation expansion, approximate quadra-ture.
