A unified approach to systemic risk measures via acceptance sets

F Biagini, JP Fouque, M Frittelli… - Mathematical …, 2019 - Wiley Online Library
We specify a general methodological framework for systemic risk measures via
multidimensional acceptance sets and aggregation functions. Existing systemic risk …

Dual representation of quasi-convex conditional maps

M Frittelli, M Maggis - SIAM Journal on Financial Mathematics, 2011 - SIAM
We provide a dual representation of quasi-convex maps π:L_F%→L_G, between two locally
convex lattices of random variables, in terms of conditional expectations. This generalizes …

[HTML][HTML] The algebra of conditional sets and the concepts of conditional topology and compactness

S Drapeau, A Jamneshan, M Karliczek… - Journal of Mathematical …, 2016 - Elsevier
The concepts of a conditional set, a conditional inclusion relation and a conditional
Cartesian product are introduced. The resulting conditional set theory is sufficiently rich in …

Conditional systemic risk measures

A Doldi, M Frittelli - SIAM Journal on Financial Mathematics, 2021 - SIAM
We investigate to which extent the relevant features of (static) Systemic Risk Measures can
be extended to a conditional setting. After providing a general dual representation result, we …

A survey of time consistency of dynamic risk measures and dynamic performance measures in discrete time: LM-measure perspective

TR Bielecki, I Cialenco, M Pitera - Probability, Uncertainty and Quantitative …, 2017 - Springer
In this work we give a comprehensive overview of the time consistency property of dynamic
risk and performance measures, focusing on a the discrete time setup. The two key …

On random convex analysis

T Guo, E Zhang, M Wu, B Yang, G Yuan… - arXiv preprint arXiv …, 2016 - arxiv.org
Recently, based on the idea of randomizing space theory, random convex analysis has
been being developed in order to deal with the corresponding problems in random …

Acceptability indexes via-expectations: an application to liquidity risk

E Rosazza Gianin, C Sgarra - Mathematics and financial economics, 2013 - Springer
Recently, several authors focused their attention on acceptability indexes (AI) and their
applications in Finance. The AI notion turns out to be quite flexible and several applications …

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
First, this paper introduces the notion of L 0-convex compactness for a special class of
closed convex subsets–closed L 0-convex subsets of a Hausdorff topological module over …

[HTML][HTML] Conditionally evenly convex sets and evenly quasi-convex maps

M Frittelli, M Maggis - Journal of Mathematical Analysis and Applications, 2014 - Elsevier
Evenly convex sets in a topological vector space are defined as the intersection of a family of
open half spaces. We introduce a generalization of this concept in the conditional framework …

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 …
