Multidimensional sampling-Kantorovich operators in BV-spaces

Autor: Angeloni Laura, Vinti Gianluca

Publikováno v: Open Mathematics, Vol 21, Iss 1, Pp 41-56 (2023)

The main purpose of this article is to prove a result of convergence in variation for a family of multidimensional sampling-Kantorovich operators in the case of averaged-type kernels. The setting in which we work is that one of BV-spaces in the sense

General relativity predicts that black holes are described by the Kerr metric, which has integrable geodesics. This property is crucial to produce accurate waveforms from extreme-mass-ratio inspirals. Astrophysical environments, modifications of grav
