NettetAs Fourier transformations of Lp functions are the mathematical basis of various applications, it is necessary to develop Lp theory for 2D-LCT before any further rigorous mathematical investigation of such transformations. In this paper, we study this Lp theory for 1≤p<∞. By defining an appropriate convolution, we obtain a result about the inverse … Nettet1. mar. 2004 · Vogel (1985) used the GCV criterion in a Newton-type solution to a simplified inverse scattering problem; Amato & Hughes (1991) used the GCV criterion in the inversion of the standard Fredholm integral equation of the first kind, which was non-linear because of their choice of an entropy measure as the regularization term; and …

In mathematics, the bounded inverse theorem (or inverse mapping theorem) is a result in the theory of bounded linear operators on Banach spaces. It states that a bijective bounded linear operator T from one Banach space to another has bounded inverse T . It is equivalent to both the open mapping theorem and the closed graph theorem.
