The Classical Theory of Real Functions
1998
The first class of real functions we deal with in this chapter is the class of functions of locally finite variation. These functions are closely related to the real measures on B. Exploiting this connection would allow us to obtain the properties of these functions from the general results in Chapter 4. But the path we follow here is a more direct one which applies the theory of vector lattices. The link with the measures on B will be established in the next section.
On the inductive inference of recursive real-valued functions
1999
AbstractWe combine traditional studies of inductive inference and classical continuous mathematics to produce a study of learning real-valued functions. We consider two possible ways to model the learning by example of functions with domain and range the real numbers. The first approach considers functions as represented by computable analytic functions. The second considers arbitrary computable functions of recursive real numbers. In each case we find natural examples of learnable classes of functions and unlearnable classes of functions.
ON THE FUNDAMENTAL THEOREM OF CALCULUS FOR FRACTAL SETS
2015
The aim of this paper is to formulate the best version of the Fundamental theorem of Calculus for real functions on a fractal subset of the real line. In order to do that an integral of Henstock–Kurzweil type is introduced.
Leonida Tonelli: A Biography
2011
This paper aims at going through the work by Leonida Tonelli, with a focus on the results he got in the fields of Real Analysis and Calculus of Variations, and put it within the socio-political context of his time. One of the most outstanding Italian analysts in the first half of twentieth century, first in Bologna and then in Pisa and Rome, Leonida Tonelli’s path combined elements of different, conflictual in some moment, relationships which featured at that time Italian mathematics and which linked the latter with Giovanni Gentile, the Fascism and the after-war “new”Italy.
Higher Order Sobolev-Type Spaces on the Real Line
2014
This paper gives a characterization of Sobolev functions on the real line by means of pointwise inequalities involving finite differences. This is also shown to apply to more general Orlicz-Sobolev, Lorentz-Sobolev, and Lorentz-Karamata-Sobolev spaces.
