Especially, the isometric mapping property of Hsub(v) which holds on L²(IRsub(+),rdr) is extended to spaces of arbitrary Sobolev order. The novelty in the approach consists in using techniques developed by B.-W. Schulze and others to treat the half-line Rsub(+) as a manifold with a conical singularity at r = 0. This is achieved by pointing out a connection between the Hankel transformation and the Mellin transformation.The procedure proposed leads at the same time to a short proof of the Hankel inversion formula. An application to the existence and higher regularity of solutions, including their asymptotics, to the 1-1-dimensional edge-degenerated wave equation is given.

Recently analogous results were obtained for functions of several variables. The aim of this paper is to comprehend the theorem of Bohr in the context of solutions to second order elliptic equations meeting the maximum principle.

We show that expansions in homogeneous functions are always stable on a small ball around the origin, and evaluate the radius of the largest ball with this property.

N2 - The COVID-19 pandemic has revealed the importance for university teachers to have adequate pedagogical and technological competences to cope with the various possible educational scenarios (face-to-face, online, hybrid, etc.), making use of appropriate active learning methodologies and supporting technologies to foster a more effective learning environment. In this context, the InnovaT project has been an important initiative to support the development of pedagogical and technological competences of university teachers in Latin America through several trainings aiming to promote teacher innovation. These trainings combined synchronous online training through webinars and workshops with asynchronous online training through the MOOC “Innovative Teaching in Higher Education.” This MOOC was released twice. The first run took place right during the lockdown of 2020, when Latin American teachers needed urgent training to move to emergency remote teaching overnight. The second run took place in 2022 with the return to face-to-face teaching and the implementation of hybrid educational models. This article shares the results of the design of the MOOC considering the constraints derived from the lockdowns applied in each country, the lessons learned from the delivery of such a MOOC to Latin American university teachers, and the results of the two runs of the MOOC.

A Historiographical and Linguistic Study JF - Sprache Deutsch PaRDeS : Zeitschrift der Vereinigung für Jüdische Studien [23 (2017)] = JewBus, Jewish Hindus & other Jewish Encounters with East Asian Religions JF - PaRDeS : Journal of the Association of Jewish Studies [23 (2017)] = JewBus, Jewish Hindus & other Jewish Encounters with East Asian Religions N2 - This article deals with contact between East Asian thought and modern Hebrew Literature from the late nineteenth century through the twentieth century, until today. In the first part, the article suggests that from a historiographical perspective, one may outline three waves of contact between these two cultural phenomena, at opposite ends of Asia. In the first wave, which began in the early twentieth century, Asian influence on Hebrew literature written in Europe was mediated mainly through the philosophers Schopenhauer and Nietzsche. The second wave, which emerged in the 1950s, relates to the influence of the leaders of the Beat Generation, who, in turn, were influenced by modernist poetry in English, which was colored by contact with Asian poetry. The third wave is part of the glocal New Age phenomenon and its appropriation of certain Buddhist traits. The second part of the article presents several theoretical possibilities of symbioses between cultures, as they appear within language. The third part presents the symptomatic example of the work of contemporary Hebrew writer Yoel Hoffmann, who appears to be a representative of the second wave; however, his work maintains dialogue with the first wave, and its current popularity is part of the third wave. Hoffmann’s work serves as an example of how to apply the theoretical possibilities presented in the second part of the article, as an instance of literary contact between two cultures and their respective languages.

N2 - Yoel Hoffmann is an Israeli writer born in 1937 in Brasov (Kronstadt), Romania. Brought up in a German-speaking family, already in his first book, Sefer Yosef (1989), he conveys the voice of German-speaking immigrants in Israel (the “Katschen” story, 1986) and that of the East European Jewish community in Berlin in the late 1930s, on the verge of the Second World War. His works are crammed with characters of Jews from Germany gripped by the memory of the language they abandoned following their emigration to Palestine in the 1930s. The classic one is the character of Bernhard, in the eponymous work. The current article focuses on the representation and elaboration of Hoffmann’s unique creation, in a language influenced by his deep identification with Zen Buddhism on the one hand, and his attraction to the modernist, Western style of stream of consciousness on the other. In central sections of his works, Hoffman presents his entire literary corpus as a type of explicit, allusive, or secret Holocaust literature, and invites his readers and his critics to decode the allusions and expose the secret in this theme, a surprising statement in relation to Hoffmann’s work and its analysis so far. Hoffmann represents the Holocaust as a collective Israeli trauma for which his literary fiction creates a special catalogue of representative characters. In the creation of a catalogue, and particularly one that simultaneously classifies and individualizes, Hoffmann’s project resembles the monumental 1920s cataloguing project by the celebrated German photographer August Sander (Menschen des 20. Jahrhunderts). Hoffmann included photographs from this project in his works, and even chose some of them for the covers of his books. The article examines the implicit relationships between these two creative artists as conferring a meaning so far not considered in the research of the Holocaust theme in Yoel Hoffmann’s writings. N2 - Yoel Hoffmann ist ein israelischer Autor, der 1937 in Brasov (Kronstadt), Rumänien geboren wurde. Er wuchs in einer deutschsprachigen Familie auf. Bereits in seinem ersten Buch Sefer Yosef (1989) verleiht er den deutschsprachigen Immigranten in Israel (die „Katschen”-Geschichte, 1986) und der osteuropäisch-jüdischen Gemeinschaft im Berlin der späten 1930er Jahre vor Ausbruch des Zweiten Weltkriegs eine Stimme. Sein Werk ist mit jüdischen Protagonisten aus Deutschland gespickt, die von der Erinnerung an die Sprache erfasst sind, von der sie sich seit ihrer Emigration nach Palästina in den 1930er Jahren zu lösen versuchen. Ein klassisches Beispiel hierfür ist die Figur des Bernhard in Hoffmanns gleichnamigem Werk. Der folgende Artikel fokussiert die Darstellungsweise und Ausarbeitung von Hoffmanns einzigartigem Werk, dessen Sprache einerseits durch seine tiefe Identifikation mit dem Zen Buddhismus und andererseits durch einen den Autor anziehenden, modernistischen westlichen Stil des Bewusstseinsstroms beeinflusst wurde. In zentralen Teilen seines Werkes stellt Hoffmann seinen gesamten literarischen Textkorpus als einen Typus der expliziten, anspielenden oder aber verborgenen Holocaust-Literatur dar. Er lädt seine Leserschaft und seine Kritiker dazu ein, seine Anspielungen zu dechiffrieren und das Geheimnis seiner Themen aufzudecken. Dies ist eine überraschende Aussage in Bezug auf Hoffmanns Werk und dessen bisherige Analyse. Der Autor stellt den Holocaust als ein kollektives israelisches Trauma dar, für das seine literarische Fiktion einen speziellen Katalog repräsentativer Charaktere erstellt hat. Bei der Erstellung dieses Katalogs, dies insbesondere da er zeitgleich klassifiziert und individualisiert, ähnelt Hoffmanns Projekt dem monumentalen Katalogisierungsprojekt der 1920er Jahre, das von dem gefeierten deutschen Fotografen August Sander (Menschen des 20. Jahrhunderts) durchgeführt wurde. Hoffmann bezieht Fotografien aus Sanders Projekt in sein Werk ein und verwendet sogar einige der Abbildungen für die Titelseite seiner Bücher. Der Artikel behandelt die implizite Beziehung zwischen diesen beiden kreativen Künstlern und lässt diesem Aspekt eine Bedeutung zuteil werden, die bislang in der Forschung über Holocaust Themen in Yoel Hoffmanns schriftstellerischem Werk keinen Niederschlag fand.

The calamitic LCs investigated were found to form monolayers which behave analogously to conventional amphiphiles such as fatty acids. The spreading of the discotic LCs produced monolayers as well, but with a behaviour different from classical amphiphiles. The areas occupied per molecule are too small to allow the contact of all hydrophilic groups with the water surface and the packing of all hydrophobic chains. Various molecular arrangements of the discotics at the water surface to fit the spreading data are discussed.
