    Deriving the dependence structure of portfolio credit derivatives using evolutionary algorithms

    Even if the correct modeling of default dependence is essential for the valuation of portfolio credit derivatives, for the pricing of synthetic CDOs a one-factor Gaussian copula model with constant and equalpairwise correlationsfor all assets in the reference portfolio has become the standard market model. If this model were a re?ection of market opinion, there wouldn't be the implied correlation smilethatis observedinthe market. Thepurposeof thispaperistoderive a correlation structure from observed CDO tranche spreads. The correlation structure is chosen such that all tranche spreads of the traded CDO can be reproduced. This implied correlation structure can then be used to price o?-market tranches with the same underlying as the traded CDO. Using this approach we can significantly reduce the risk to misprice o?-market derivatives. Due to the complexity of the optimization problem we apply Evolutionary Algorithms. --

    Risk preference based option pricing in a fractional Brownian market

    No full text
    We focus on a preference based approach when pricing options in a market driven by fractional Brownian motion. Within this framework we derive formulae for fractional European options using the traditional idea of conditional expectation. The obtained formulae - as well as further results - accord with classical Brownian theory and con?rm economic intuition towards fractional Brownian motion. Furthermore the in?uence of the Hurst parameter H on the price of a European option will be analyzed. --Fractional Brownian motion,Conditional expectation,Risk preference based option pricing,Fractional option pricing,Fractional Greeks

    Eros and Thanatos: A psycho-literary investigation of Walter Vogt\u27s life and works

    No full text
    The Swiss author Walter Vogt was a medical doctor and a practicing psychiatrist. The approach applied to the investigation of his life and works is determined by the fact that the author of this dissertation is also a medical doctor and a psychiatrist. Vogt is not only a colleague of his, then, with an abundant literary productivity, but can also be viewed as a patient haunted by a multitude of psychological and somatic problems. ^ Vogt\u27s works are distinguished by an unusually close interrelationship between his real-life experience and the fictional world of his narrative prose. Certain conclusions will therefore be reached based not only on the literary texts but also on the psychological evidence derived from conversations and correspondence with professional colleagues and members of Vogt\u27s family. ^ The dissertation initially presents the major problems experienced and transferred into art by Walter Vogt. These problems are related to his medical profession as well as to his personal drug addiction.^ The succeeding basis for discussion is Vogt\u27s astounding productivity after he had almost destroyed himself by his addictive use of drugs, then freeing himself from addiction. Dealing with his works requires an ongoing alternation between the fiction of the stories and the facts of psychiatric case histories. ^ To fully understand Vogt\u27s works, his physical illnesses and sexual issues as well as his attempts to become an acclaimed literary success must be analyzed. His self-destructive behavior is presented in the overall context of his psychological problems. Vogt was vacillating between eros, the sum of self-preservation, and thanatos, the instinct to self-destruct. An assumption that Vogt was schizophrenic, however, is not justifiable, based on the medical evidence. ^ In the baffling world of competing inner forces, we find that Vogt, as a psychiatric doctor, failed to treat himself as he would have treated his own patients. The sole means by which a disintegration of Vogt\u27s psyche was averted was his writing, which absorbed the destructive elements in his personal life.

    Cultural Policy against the Grain 流れに逆らう文化政策: liber amicorum for Matthias Theodor Vogt in honour of his 65th birthday, edited by his colleagues and students

    What are the premises of today‘s cultural policy? What insights can the past, present and theory offer for a contemporary cultural policy? How can art counteract agoraphobia, digital isolation and populist temptations? How can local authorities give their citizens ample space to develop civil society solidarity ‘for the good of the city. For only when the city is well will you be well.’ (It should be noted that Jeremiah 29:7 addresses immigrants who are to become citizens in foreign Babylon. Does our cultural policy also achieve this?) Are the arts not precisely the place where we can first listen to the other before we think together and then act together?It is the historical achievement of Matthias Theodor Vogt, in the Free State of Saxony, which was re-established in 1990, to not only conceive the Saxon Cultural Area Act between 1991 and 1995 in a unique process of analysis and dialogue with the state, municipal and civil society levels, but also to have it enshrined in law and, last but not least, to have it implemented with little friction. It was therefore only natural that, on the thirtieth anniversary of the law‘s entry into force, the cultural areas of Saxony invited Matthias Theodor Vogt‘s colleagues and students to a conference entitled ‘Kulturpolitik gegen den Strich’ (Cultural Policy Against the Grain). We are hereby presenting the results of this conference in a commemorative publication to mark his 65th birthday.What can art do better and differently than the digital world? What political, structural, economic, and, last but not least, intellectual conditions are necessary for art to develop its own life for the benefit of humanity? The cover image shows Haus Klingewalde, Görlitz, home of the Institute for Cultural Infrastructure Saxony since 1998. The watercolour by Lynne Beal, Cologne, relates to a conversation with Matthias Theodor Vogt about the vanishing point in Alberti: De pictura | De pittura (1435 – 1436). According to Corinna Laude, in the centricus punctus of Alberti‘s intromission theory, ‘the orthogonal vanishing lines, the depth lines of the representation, converge “quasi persino in infinito” (as it were out into infinity), it lies in infinity – and thus, according to contemporary understanding, in God’. Which “vanishing points” does today‘s post-secular society use?How can political science in Chemnitz interact in a multidisciplinary, cross-continental manner, always with reference to human beings themselves, with cultural studies in Tokyo and linguistics in Leipzig, with legal studies in Naples and social sciences in Rome?

    Galactosamine and mannosamine are integral parts of bacterial and fungal extracellular polymeric substances

    No full text
    Extracellular polymeric substances (EPS) are produced by microorganisms and interact to form a complex matrix called biofilm. In soils, EPS are important contributors to the microbial necromass and, thus, to soil organic carbon (SOC). Amino sugars (AS) are used as indicators for microbial necromass in soil, although the origin of galactosamine and mannosamine is largely unknown. However, indications exist that they are part of EPS. In this study, two bacteria and two fungi were grown in starch medium either with or without a quartz matrix to induce EPS production. Each culture was separated in two fractions: one that directly underwent AS extraction (containing AS from both biomass and EPS), and another that first had EPS extracted, followed then by AS determination (exclusively containing AS from EPS). We did not observe a general effect of the quartz matrix neither of microbial type on AS production. The quantified amounts of galactosamine and mannosamine in the EPS fraction represented on average 100% of the total amounts of these two AS quantified in cell cultures, revealing they are integral parts of the biofilm. In contrast, muramic acid and glucosamine were also quantified in the EPS, but with much lower contribution rates to total AS production, of 18% and 33%, respectively, indicating they are not necessarily part of EPS. Our results allow a meaningful ecological interpretation of mannosamine and galactosamine data in the future as indicators of microbial EPS, and also attract interest of future studies to investigate the role of EPS to SOC and its dynamics

    Über Operaden

    This Thesis consists of four independent parts. In the first part I prove that the delooping, i.e.the classifying space, of a grouplike monoid is an HH-space if and only if its multiplication is a homotopy homomorphism. This is an extension and clarification of a result of Sugawara. Furthermore I prove that the Moore loop space functor and the construction of the classifying space induce an adjunction on the corresponding homotopy categories. In the second part I extend a result of G. Dunn, by proving that the tensorproduct Cn1CnjC_{n_1}\otimes\dots \otimes C_{n_j} of little cube operads is a topologically equivalent suboperad of Cn1njC_{n_1 \dots n_j}. In the third part I describe operads as algebras over a certain colored operad. By application of results of Boardman and Vogt I describe a model of the homotopy category of topological operads and algebras over them, as well as a notion of lax operads, i.e. operads whose axioms are weakened up to coherent homotopies. Here the W-construction, a functorial cofibrant replacement for a topological operad, plays a central role. As one application I construct a model for the homotopy category of topological categories. C. Berger claimed to have constructed an operad structure on the permutohedras, whose associated monad is exactly the Milgram-construction of the free two-fold loop space. In the fourth part I prove that this statement is not correct
