An absolute continuity for positive operators on Banach lattices

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1991
For positive operators on a Banach lattice, absolute contnuity conditions are considered. An operator absolutely continuous with respect to T is compared to sums of compositions of T together with orthomorphisms or in special cases projections ...

On Absolute Continuity of Conjugations between Circle Maps with Break Points

open access: yesAbstract and Applied Analysis, 2012
Let T1 and T2 be piecewise smooth circle homeomorphisms with break points and identical irrational rotation numbers. We provide one sufficient and necessary condition for the absolute continuity of conjugation map between T1 and T2.

Some remarks on descriptive characterizations of the strong McShane integral [PDF]

open access: yesMathematica Bohemica, 2019
We present the full descriptive characterizations of the strong McShane integral (or the variational McShane integral) of a Banach space valued function $f W \to X$ defined on a non-degenerate closed subinterval $W$ of $\mathbb{R}^m$ in terms of strong ...

Pointwise Differentiability and Absolute Continuity [PDF]

open access: yesTransactions of the American Mathematical Society, 1974
This paper is concerned with the relationships between L p {L_p} differentiability and Sobolev functions. It is shown that if f is a Sobolev function with weak derivatives up to order k in L p {L_p} , and 0 ≤ l ≤

ON MEAN DENSITIES OF INHOMOGENEOUS GEOMETRIC PROCESSES ARISING IN MATERIAL SCIENCE AND MEDICINE

open access: yesImage Analysis and Stereology, 2011
The scope of this paper is to offer an overview of the main results obtained by the authors in recent literature in connection with the introduction of a Delta formalism, á la Dirac-Schwartz, for random generalized functions (distributions) associated ...

On one condition of absolutely continuous spectrum for self-adjoint operators and its applications [PDF]

open access: yesOpuscula Mathematica, 2018
In this work the method of analyzing of the absolutely continuous spectrum for self-adjoint operators is considered. For the analysis it is used an approximation of a self-adjoint operator \(A\) by a sequence of operators \(A_n\) with absolutely ...

The material Advance of the old Idealism

open access: yesPensamiento. Revista de Investigación e Información Filosófica, 2019
The current article aims at drawing the line of speculative continuity that connects the absolute idealism with what some authors have called the last materialist program of the old German idealism.

The mind-body problem between philosophy and the cognitive sciences

open access: yesRivista Internazionale di Filosofia e Psicologia, 2023
Here, I examine the main philosophical solutions to the mind-body problem distinguishing between “historicist” solutions that (more or less clearly) separate philosophy from science and solutions that instead result from a double “cognitive turn”, and ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
