Douglas' Factorization Theorem and Atomic System in Hilbert Pro-$C^{\ast}$-Modules [PDF]

open access: yesSahand Communications in Mathematical Analysis
In the present paper, we introduce  the generalized inverse operators, which have an exciting role in operator theory. We establish Douglas' factorization theorem type  for  the Hilbert pro-$C^{\ast}$-module.We introduce the notion of atomic system and ...

ON FAMILIES IN DIFFERENTIAL GEOMETRY [PDF]

open access: yesInternational Journal of Geometric Methods in Modern Physics, 2013
Families of objects appear in several contexts, like algebraic topology, theory of deformations, theoretical physics, etc. An unified coordinate-free algebraic framework for families of geometrical quantities is presented here, which allows one to work without introducing ad hoc spaces, by using the language of differential calculus over commutative ...

Hypergraph p-Laplacian: A Differential Geometry View [PDF]

open access: yesAAAI Conference on Artificial Intelligence, 2017
The graph Laplacian plays key roles in information processing of relational data, and has analogies with the Laplacian in differential geometry.

Evaluation of Linearization Methods for Control of the Pendubot

open access: yesApplied Sciences, 2021
The aim of this paper is to test the usefulness of a new approach based on partial feedback linearization to control the Pendubot. The control problem stated in the article is to stabilize the Pendubot in the upright position.

Differential Invariants in a General Differential Geometry [PDF]

open access: yesProceedings of the National Academy of Sciences, 1937
The study of general differential geometries in which the "geometric space" is a Hausdorff topological space~), while the "coordinate space" i~ a Banach space 3), has been initiated recently by one of us ~). The theory includes as special cases not only the finite dimensional but also the infinite dimensional 5) Riemannian and Non-Riemannian geometries.

On the differential geometry of [PDF]

open access: yesJournal of Physics A: Mathematical and General, 1998
The differential calculus on the quantum supergroup GL$_q(1| 1)$ was introduced by Schmidke {\it et al}. (1990 {\it Z. Phys. C} {\bf 48} 249). We construct a differential calculus on the quantum supergroup GL$_q(1| 1)$ in a different way and we obtain its quantum superalgebra. The main structures are derived without an R-matrix.

Nonlinear Observability Algorithms with Known and Unknown Inputs: Analysis and Implementation

open access: yesMathematics, 2020
The observability of a dynamical system is affected by the presence of external inputs, either known (such as control actions) or unknown (disturbances).

Differential geometry via infinitesimal displacements

open access: yes, 2015
We present a new formulation of some basic differential geometric notions on a smooth manifold M, in the setting of nonstandard analysis. In place of classical vector fields, for which one needs to construct the tangent bundle of M, we define a prevector

AV-differential geometry and Newtonian mechanics [PDF]

open access: yes, 2006
A frame independent formulation of analytical mechanics in the Newtonian space-time is presented The differential geometry of affine values i.e., the differential geometry in which affine bundles replace vector bundles and sections of one dimensional ...

Principles of Differential Geometry

open access: yesarXiv: History and Overview, 2016
The present text is a collection of notes about differential geometry prepared to some extent as part of tutorials about topics and applications related to tensor calculus. They can be regarded as continuation to the previous notes on tensor calculus as they are based on the materials and conventions given in those documents.
