Multifunctions of bounded variation [PDF]

open access: yesJournal of Differential Equations, 2016
Abstract Consider control systems described by a differential equation with a control term or, more generally, by a differential inclusion with velocity set F ( t , x ) . Certain properties of state trajectories can be derived when it is assumed that F ( t , x ) is merely measurable w.r.t. the time variable t.

On functions of bounded variation [PDF]

open access: yesMathematical Proceedings of the Cambridge Philosophical Society, 2016
AbstractThe recently introduced concept of ${\mathcal D}$-variation unifies previous concepts of variation of multivariate functions. In this paper, we give an affirmative answer to the open question from [20] whether every function of bounded Hardy–Krause variation is Borel measurable and has bounded ${\mathcal D}$-variation.

Generalized Bounded Variation and Inserting point masses [PDF]

open access: yes, 2008
Let $d\mu$ be a probability measure on the unit circle and $d\nu$ be the measure formed by adding a pure point to $d\mu$. We give a simple formula for the Verblunsky coefficients of $d\nu$ based on a result of Simon.

On Bounded Second Variation [PDF]

open access: yesAdvances in Pure Mathematics, 2012
In this paper, we discuss various aspects of the problem of space-invariance, under compositions, of certain subclasses of the space of all continuously differentiable functions on an interval [a,b] We present a result about integrability of products of the form gοf.f'f(k)under suitable mild conditions and, finally, we prove that a Nemytskij operator ...

Properties of the solutions of delocalised coagulation and inception problems with outflow boundaries [PDF]

open access: yes, 2015
Well posedness is established for a family of equations modelling particle populations undergoing delocalised coagulation, advection, inflow and outflow in a externally specified velocity field.

On integral bounded variation [PDF]

open access: yesRevista de la Real Academia de Ciencias Exactas, Físicas y Naturales. Serie A. Matemáticas, 2017
In this paper we will investigate the concept of the q-integral p-variation introduced in 1970’s by Terehin. This kind of integral variation has been mainly used, until now, to describe the regularity of functions in $$L^p$$

ON THE DERIVATIVES OF FUNCTIONS OF BOUNDED VARIATION [PDF]

open access: yesReal Analysis Exchange, 2000
Using a standard complete metric $w$ on the set $F$ of continuous functions of bounded variation on the interval $[0,1]$, we find that a typical function in $F$ has an infinite derivative at continuum many points in every subinterval of $[0,1]$.

BOUNDED VARIATION ON THE SIERPIŃSKI GASKET

open access: yesFractals, 2022
Under certain continuity conditions, we estimate upper and lower box dimensions of the graph of a function defined on the Sierpiński gasket. We also give an upper bound for Hausdorff dimension and box dimension of the graph of a function having finite energy.

Bounded variation and relaxed curvature of surfaces

open access: yes, 2020
We consider a relaxed notion of energy of non-parametric codimension one surfaces that takes account of area, mean curvature, and Gauss curvature. It is given by the best value obtained by approximation with inscribed polyhedral surfaces.
