Functions of bounded variation

open access: yes, 2006
The paper begins with a short survey of monotone functions. The functions of bounded variation are introduced and some basic properties of these functions are given. Finally the jump function of a function of bounded variation is defined.

Homeomorphisms of Bounded Variation

Archive for Rational Mechanics and Analysis, 2007
The main result of the paper is that if \(\Omega, \Omega' \subset \mathbb R^2\) are open and \(f:\Omega \to \Omega'\) is a homeomorphism, then \(f\in BV_{loc}(\Omega,\mathbb R^2)\) if and only if \(f^{-1}\in BV_{loc}(\Omega',\mathbb R^2)\). It is shown that this result does not extend to the case of \(\mathbb R^n\) with \(n\geq 3\).

Functions of Bounded Variation�and Rearrangements

Archive for Rational Mechanics and Analysis, 2002
The authors study the properties of the symmetric rearrangement \(u^*\) of a function \(u\) when \(u\) is of bounded variation in \({\mathbb R}^n\). Among these properties, the continuity and the approximate differentiability of \(u^*\) on the level sets \(\{u^*=t\}\) is investigated.

Are Natural Images of Bounded Variation?

SIAM Journal on Mathematical Analysis, 2001
Summary: The bounded variation assumption is the starting point of many methods in image analysis and processing. However, one common drawback of these methods is their inability to handle textures and small structures properly. Here we precisely show why natural images are incompletely represented by BV functions.

A generalization of bounded variation

Acta Mathematica Hungarica, 1990
The notion of bounded \(p\)-variation was introduced by \textit{N. Wiener} in 1924 [see Mass. J. Math. 3, 72--94 (1924; JFM 50.0203.01)]. \textit{D. Waterman} [Stud. Math. 44, 107--117 (1972; Zbl 0207.06901)] and \textit{Z. A. Chanturiya} [Dokl. Akad. Nauk SSSR 214, 63--66 (1974; Zbl 0295.26008)] have made important contributions concerning the concept

Variational bounds for the triton

Physical Review C, 1987
Variational bounds for the Reid soft core and Argonne V/sub 14/ potentials are extended through the J = 8 partial waves of those nucleon-nucleon forces using Faddeev wave functions calculated with the Jless than or equal to4 partial waves. We verify our previous conjecture that the additional components add roughly 10 keV to the binding energy, and ...

Functions of bounded variation and polarization

Mathematische Nachrichten, 2009
AbstractIt is known that, ifuis a real valued function on ℝNof bounded variation, then its total variation decreases under polarization. In this paper we identify the difference between the total variation ofuand that one of its polaruΠ(© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
