Conditional Lp-spaces and the duality of modules over f-algebras
No full textMotivated by dynamic asset pricing, we extend the dual pairs’ theory of Dieudonné (1942) and Mackey (1945) to pairs of modules over a Dedekind complete f-algebra with multiplicative unit. The main tools are:
- a Hahn–Banach Theorem for modules of this kind;
- a topology on the f-algebra that has the special feature of coinciding with the norm topology when the algebra is a Banach algebra and with the strong order topology of Filipovic, Kupper, and Vogelpoth (2009), when the algebra of all random variables on a probability space (Ω, G, P) is considered.
As a leading example, we study in some detail the duality of conditional Lp-spaces

New Necklaces: 400 Designs in Contemporary Jewellery
No full textAfter the successful New Rings and New Earrings, New Necklaces is the third book curated by jeweller and author Nicolas Estrada, from classic forms and materials to the most daring, experimental and surprising ideas, each of the 500 necklaces included in this book has something that makes it unique and relates strongly to today's social, cultural and artistic reality. With prefaces by German jeweller Julia Wild and Leo Caballero, owner of the Barcelona gallery Klimt 02, specialised in contemporary jewellers
How Did I Get to Princess Margaret? (And How Did I Get Her to the World Wide Web?)
No full textThe paper explores the growing use of
tools from the arts and humanities for investigation
and dissemination of social science research.
Emerging spaces for knowledge transfer, such as
the World Wide Web, are explored as outlets for
"performative social science". Questions of ethnics
and questions of evaluation which emerge from
performative social science and the use of new
technologies are discussed. Contemporary thinking
in aesthetics is explored to answer questions
of evaluation. The use of the Internet for productions
is proposed as supporting the collective
elaboration of meaning supported by Relational
Aesthetics.
One solution to the ethical problem of performing
the narrations of others is the use of the writer's
own story as autoethnography. The author queries
autoethnography's tendency to tell "sad" stories and
proposes an amusing story, exemplified by "The
One about Princess Margaret" (see Appendix).
The conclusion is reached that the free and open
environment of the Internet sidelines the usual
tediousness of academic publishing and begins to
explore new answers to questions posed about
the evaluation and ethics of performative social
science
Identification of author profiles through social networks
No full textThe aim of this paper is to compile dictionaries of slang words, abbreviations, contractions, and emoticons to help the pre-processing of texts published in social networks. The use of these dictionaries is intended to improve the results of the tasks related to data obtained from these platforms. Therefore, a hypothesis was evaluated in the task of identifying author profiles (author profiling).Silva, JesúsMaria Santodomingo, Nicolas EliasRomero, LigiaJorge, MarisolHerrera, MaritzaPineda Lezama, Omar Bonerg
L^0-convex analysis and conditional risk measures
No full textMotiviert durch Anwendungen aus der Finanzmathematik wird in der vorliegenden Dissertation konvexe Analysis für Moduln über dem geordneten Ring L^0 aller Zufallsvariablen studiert. Dabei werden L^0-Moduln erarbeitet, die als Pendant zu lokal konvexen Vektorräumen begriffen werden können, sogenannte lokal L^0-konvexe Moduln. Für solche L^0-Moduln werden Hyperebenen Trennungssätze bewiesen.
Des weiteren werden Stetigkeits- und Subdifferenzierbarkeitseigenschaften sowie duale Darstellungen von Fenchel-Moreau Typ für L^0-konvexe Funktionen untersucht, welche L^0-Moduln nach L^0 abbilden.
Als Beispiele für lokal L^0-konvexe Moduln werden L^0-Moduln analog zu L^p und Orlicz Räumen präsentiert. Hierbei wird vor allem topologische Vollständigkeit der L^0-Moduln untersucht und im Falle des L^0-Moduls von L^p Typ wird zusätzlich das duale L^0-Modul charakterisiert. Anwendungen für Risikomaße werden beispielhaft demonstriert.
Des weiteren werden Resultate bezüglich automatischer Stetigkeit und Subdifferenzierbarkeit monotoner konvexer Funktionen, welche L^0-Moduln nach L^0 abbilden, präsentiert. Diese Resultate stellen Verallgemeinerungen von klassischen Resultaten über automatische Stetigkeit und Subdifferenzierbarkeit monotoner konvexer Funktionen und konvexer Risikomaße dar.
Als zentrale Motivation der vorliegenden Arbeit werden zwei unterschiedliche Zugänge zu bedingten Risikomaßen vorgestellt und verglichen. Während dem einen vektorraumbasierte konvexe Analysis zugrunde liegt, innerhalb dessen bedingte Risikomaße als Funktionen auf L^p Räumen verstanden werden, liegt dem anderen Zugang modulbasierte konvexe Analysis, wie in dieser Dissertation erarbeitet, zugrunde. Bei letzterem werden bedingte Risikomaße als Funktionen auf L^0-Moduln von L^p Typ verstanden.
Durch verschiedene Anwendungen, wie zum Beispiel montone (sub)cash invariante Hüllen, die im Rahmen zahlreicher Beispiele dargestellt werden, wird aufgezeigt, dass modulbasierte konvexe Analysis viele nützliche Resultate für das Konzept bedingter Risikomaße bereitstellt.Motivated by financial applications, we study convex analysis for modules over the ordered ring L^0 of random variables. We establish a module analogue of locally convex vector spaces, namely locally L^0-convex modules. In this context, we prove hyperplane separation theorems.
We investigate continuity, subdifferentiability
and Fenchel-Moreau type dual representations for L^0-convex functions from L^0-modules into L^0.
We introduce topological L^0-modules of L^p and Orlicz type. We investigate completeness and we compute the topological dual L^0-module of the L^p type L^0-module. Applications in terms of risk measures are given.
Further, we establish automatic continuity and subdifferentiability results for monotone convex functions from L^0-modules into L^0. The results are generalizations of classical results on automatic continuity and subdifferentiability of monotone convex functions and convex risk functions.
We present and compare two different approaches to conditional risk measures. One approach draws from vector space based convex analysis and presents conditional risk measures as functions on L^p spaces while the other approach utilizes module based convex analysis as presented in this thesis where conditional risk measures are defined on L^p type L^0-modules. Both approaches utilize general duality theory for vector valued convex functions in contrast to the current literature.
By presenting several applications such as monotone and (sub)cash invariant hulls with corresponding examples we illustrate that module based convex analysis is well suited to the concept of conditional risk measures
