Regularity in Topological Modules

open access: yesMathematics, 2020
The framework of Functional Analysis is the theory of topological vector spaces over the real or complex field. The natural generalization of these objects are the topological modules over topological rings.

Webbed spaces, double sequences, and the Macke convergence condition

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1999
In [3], Gilsdorf proved, for locally convex spaces, that every sequentially webbed space satisfies the Mackey convergence condition. In the more general frame of topological vector spaces, this theorem and its inverse are studied. The techniques used are

Locally convex approach spaces

open access: yesApplied General Topology, 2003
We continue the investigation of suitable structures for quantified functional analysis, by looking at the notion of local convexity in the setting of approach vector spaces as introduced in [6].

On a Certain Generalized Functional Equation for Set-Valued Functions

open access: yesMathematics, 2020
The aim of the paper is to generalize results by Sikorska on some functional equations for set-valued functions. In the paper, a tool is described for solving a generalized type of an integral-functional equation for a set-valued function F:X→cc(Y ...

A remark on generalized variational inequalities in locally convex topological vector spaces

open access: yesApplied Mathematics Letters, 1997
AbstractIn this note, a general existence theorem of generalized variational inequalities for quasi-monotone set-valued mappings in locally convex topological vector spaces has been established. Our result includes corresponding results in recent literature as special cases.

Topological properties and matrix transformations of certain ordered generalized sequence spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1995
In this note, we carry out investigations related to the mixed impact of ordering and topological structure of a locally convex solid Riesz space (X,τ) and a scalar valued sequence space λ, on the vector valued sequence space λ(X) which is formed and ...

A novel construction approach for the pore structure model principally focuses on the controllable roundness of rock particles

open access: yesDeep Underground Science and Engineering, EarlyView.
Particle rounding effects comparison of different methods: (a), (b), and (c) are the rounding results using the B‐spline curve method with different R; (d), (e), and (f) are the results of vertex rounding substitution method with different rounding radii.

Biomimetic Robotics and Intelligence: A Survey

open access: yesSmartBot, EarlyView.
Biomimetic robotics and intelligence, inspired by biological systems, integrate biology, engineering, and AI, develops robots capable of adapting to complex environments. By mimicking natural structures and cognitive processes, and employing algorithms like neural networks and genetic algorithms, these systems enhance autonomy and problem‐solving. This

A formula to calculate the spectral radius of a compact linear operator

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1997
There is a formula (Gelfand's formula) to find the spectral radius of a linear operator defined on a Banach space. That formula does not apply even in normed spaces which are not complete.

The Extremely Low Mechanical Force Generated by Nano‐Pulling Induces Global Changes in the Microtubule Network, Nuclear Morphology, and Chromatin Transcription in Neurons

open access: yesSmall, EarlyView.
Nano‐pulling induces stabilization, reorganization, and reorientation of the microtubule network. The nucleus of stretched cells experiences increased lateral tension, becomes more spherical, and develops surface grooves. At the level of gene expression regulation, changes in nuclear morphology induce global chromatin remodeling, leading to reduced ...
