A remark on Ekeland's principle in locally convex topological vector spaces

open access: yesMathematical and Computer Modelling, 1999
In this paper, we present a solution to a problem considered by Isac; we give a condition in order to assure the density of the convex hull of the set of Ekeland's points when the function is defined in a Hausdorff, locally convex topological vector space.

The Fixed Point Property of Quasi-Point-Separable Topological Vector Spaces [PDF]

open access: yesarXiv, 2022
In this paper, we introduce the concept of quasi-point-separable topological vector spaces, which has the following important properties: 1.In general, the conditions for a topological vector space to be quasi-point-separable is not very difficult to check; 2.The class of quasi-point-separable topological vector spaces is very large that includes ...

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.

The finest locally convex topology of an extended locally convex space [PDF]

open access: yesarXiv, 2022
Salas and Garcia introduced the concept of an extended locally convex space in [D. Salas and S. Tapia-Garcia. Extended seminorms and extended topological vector spaces. Topology and its Applications, 2016] which extends the idea of an extended normed space (introduced by Beer in G. Beer. Norms with infinite values.

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.

Nanoparticle Skin Penetration: Depths and Routes Modeled In‐Silico

open access: yesSmall, EarlyView.
An in‐silico human skin model based on 20 years of NP penetration studies, incorporating 19 parameters is developed. Using random forest and Kennard‐Stone sorting, the model achieves 95% accuracy, identifying hair follicle diameter as the dominant penetration factor.

Intrusion of quantum crystallography into classical lands

open access: yesActa Crystallographica Section B, EarlyView.
One hundred years after the quantum theory established position and momentum as incompatible quantities, quantum crystallography offers a way to visualize electron phase space behaviour in crystals.This article, written on the occasion of the International Year of Quantum Science and Technology, explores the development of alternative approaches to ...

Augury and Forerunner: Real‐Time Feedback Via Predictive Numerical Optimization and Input Prediction

open access: yesComputer Graphics Forum, EarlyView.
Transient information generated by solver steps can inform future objective function minimization. In Augury, we explore the impact of predictive numerical optimization by using solver history to predict future minimization solutions, reducing computational resources needed to arrive at convergent states for a broad class of gradient‐based optimization
