ON FUNCTIONS OF BOUNDED $ p$-VARIATION

Mathematics of the USSR-Izvestiya, 1968
In this article we obtain an asymptotic formula for the approximations to functions in the class (, ) by Fourier sums in the metric of (). We find sufficient conditions and also criteria for the continuity of the derivative of a function in the class . We also give some results on the Fourier coefficients of functions in the above class.

Omniscience Principles and Functions of Bounded Variation

MLQ, 2002
Omniscience principles are general statements that can be proved classically but not constructively. They are used to show that other, more subject-specific statements that imply some omniscience principle do not have a constructive proof. The strongest omniscience principle is the law of excluded middle itself.

Functions of Bounded Variation

2015
We know that if f is integrable, then the lower and upper sums of every partition F approximate its integral from below and above, and so the difference between either sum and the integral is at most \(S_{F} - s_{F} =\varOmega _{F}\), the oscillatory sum corresponding to F.

A generalization of bounded variation

Acta Mathematica Hungarica, 2002
The author proves some properties of the class \(\text{B}\Lambda(p(n)\uparrow \infty,\varphi)\). In particular he shows that if \(f\in \text{BV}(p(n)\uparrow\infty,\varphi)\), then \(f\in \text{B}\Lambda(p(n)\uparrow \infty,\varphi)\). The author establishes the exact order of the Fourier coefficients of functions in \(\text{B}\Lambda (p(n)\uparrow ...

Variational bounds to the overlap

Chemical Physics Letters, 1975
Abstract Starting from a closed expression for the overlap, variational upper and lower bounds to the overlap are derived by means of operator inequalities.

Bounded variation and sampling

2019
In this chapter, we shall consider certain problems where a function of bounded variation generates trigonometric series which are then compared with its Fourier integral. In fact, Chapter 4 in [198] is devoted to these problems. Here, the more modern term “sampling” is equivalent to the older “discretization”.
