Random convex analysis (I): separation and Fenchel-Moreau duality in random locally convex modules

T Guo, S Zhao, X Zeng - arXiv preprint arXiv:1503.08695, 2015 - arxiv.org
To provide a solid analytic foundation for the module approach to conditional risk measures,
our purpose is to establish a complete random convex analysis over random locally convex …

A counterexample shows that not every locally --convex topology is necessarily induced by a family of --seminorms

M Wu, T Guo - arXiv preprint arXiv:1501.04400, 2015 - arxiv.org
This paper constructs a counterexample showing that not every locally $ L^ 0$--convex
topology is necessarily induced by a family of $ L^ 0$--seminorms. Random convex analysis …

L0-convex compactness and its applications to random convex optimization and random variational inequalities

T Guo, E Zhang, Y Wang, M Wu - Optimization, 2021 - Taylor & Francis

On compactness in -modules

A Jamneshan, JM Zapata - arXiv preprint arXiv:1711.09785, 2017 - arxiv.org
Several results in functional analysis are extended to the setting of $ L^ 0$-modules, where
$ L^ 0$ denotes the ring of all measurable functions $ x\colon\Omega\to\mathbb {R} $. The …

A noncompact Schauder fixed point theorem in random normed modules and its applications

T Guo, Y Wang, HK Xu, GX Yuan, G Chen - Mathematische Annalen, 2024 - Springer
Motivated by the randomized version of the classical Bolzano–Weierstrass theorem, in this
paper we first introduce the notion of a random sequentially compact set in a random …

The relations among the notions of various kinds of stability and their applications

T Guo, X Mu, Q Tu - Banach Journal of Mathematical Analysis, 2024 - Springer
First, we prove that a random metric space can be isometrically embedded into a complete
random normed module, as an application it is easy to see that the notion of d-\(\sigma\) …

[HTML][HTML] Stability in locally L0-convex modules and a conditional version of James' compactness theorem

J Orihuela, JM Zapata - Journal of Mathematical Analysis and Applications, 2017 - Elsevier
Locally L 0-convex modules were introduced in Filipovic et al.(2009)[10] as the analytic
basis for the study of conditional risk measures. Later, the algebra of conditional sets was …

Versions of Eberlein-Šmulian and Amir-Lindenstrauss theorems in the framework of conditional sets

JM Zapata - Applicable Analysis and Discrete Mathematics, 2016 - JSTOR
