Box 1346 Ann Arbor, Ml 48106- 1346 ABSTRACT The arrival of a Protestant mission in Ethiopia during the 1850s marks a turning point in the history of the Falashas. Up until this point, they lived relatively isolated in the country, unaffected and unaware of the existence of world Jewry. Following this period and especially from the beginning of the twentieth century, the attention of certain Jewish individuals and organisations was drawn to the Falashas. This contact initiated a period of external interference which would ultimately transform the Falashas, an Ethiopian phenomenon, into Ethiopian Jews, whose culture, religion and identity became increasingly connected with that of world Jewry. It is the purpose of this thesis to examine the external influences that implemented and continued the process of transformation in Falasha society which culminated in their eventual emigration to Israel. -

Induction proofs and the difficult combinatorics are unchanged compared with D = 2, but the renormalisation – performed according to Zimmermann – is much more involved. As main result we prove that the Schwinger 2-point function resulting from 3 the ΦD-QFT model on Moyal space satisfies, for real coupling constant, reflection positivity in D = 4 and D = 6 dimensions. The K¨all´en-Lehmann mass spectrum of the associated Wightman 2-point function describes a scattering part p 2 2µ2 | | ≥ and an isolated fuzzy mass shell around p 2 = µ2. | | 1 Introduction arXiv:1612.07584v2 [math-ph] 2 Jun 2017 The Kontsevich model [1, 2] is of paramount importance because it elegantly proves Witten’s conjecture [3] about the equivalence of two approaches to quantum gravity in two dimensions: the Hermitean one-matrix model [4, 5, 6] versus the intersection theory on the moduli space of Riemann surfaces [7, 8, 9]. -

We are made out of experiences of achievement, disappointment, hope, fear, and millions and billions and trillions of other things. All these little fragments put together are what we call our self and our life. Our pride of self-existence or sense of being is by no means one entity. It is a heap, a pile of stuff.

Dispersion Relations in Gauge Theories with Confinement
EFI 95-54 MPI-Ph/95-82 Dispersion Relations in Gauge Theories with Confinement 1 Reinhard Oehme Enrico Fermi Institute and Department of Physics University of Chicago, Chicago, Illinois, 60637, USA 2 and Max-Planck-Institut f¨ur Physik - Werner-Heisenberg-Institut - 80805 Munich, Germany Abstract The analytic structure of physical amplitudes is considered for gauge the- ories with confinement of excitations corresponding to the elementary fields. Confinement is defined in terms of the BRST algebra. BRST-invariant, local, composite fields are introduced, which interpolate between physical asymp- totic states. It is shown that the singularities of physical amplitudes are arXiv:hep-th/9511007v1 1 Nov 1995 the same as in an effective theory with only physical fields. In particular, there are no structure singularities (anomalous thresholds) associated with confined constituents, like quarks and gluons. The old proofs of dispersion relations for hadronic amplitudes remain valid in QCD. 1Plenary talk presented at the XVIIIth International Workshop on High Energy Physics and Field Theory, Moscow-Protvino, June 1995. To be published in the Proceedings. 2Permanent Address It is the purpose of this talk, to give a survey of the problems involved in the derivation of analytic properties of physical amplitudes in gauge theories with confinement. This report is restricted to a brief resum´eof the essential points discussed in the talk. 3 Dispersion relations for amplitudes describing reactions between hadrons, and for form factors describing the structure of particles, have long played an important rˆole in particle physics [3, 4, 5, 6]. Analytic properties of Green’s functions are fundamental for proving many important results in quantum field theory. -
THE GRADUATE CENTER Ph.D. PROGRAM in HISTORY
THE GRADUATE CENTER Ph.D. PROGRAM IN HISTORY GLOBALIZING THE ENLIGHTENMENT Hist 72800 MALS 70600 Professor Helena Rosenblatt Tuesdays, 4:15-6:15 [email protected] Course Description: The Eighteenth Century European Enlightenment is widely seen as a transformative moment in Western culture, one which gave birth to many of our most cherished ideals. We are often told, for example, that it is to the Enlightenment that we owe our modern notions of human rights, representative government, and liberal democracy. However, the recent “global turn” in scholarship has led historians to ask some new and often unsettling questions. How, for example, did eighteenth-century European thinkers perceive the world beyond their own borders? How did they get their information and to what purposes was that information put? Did regions outside of Europe experience an Enlightenment too? With the help of both primary and secondary sources, we will ask how adopting a “global” perspective on the Enlightenment might change our view of it. Is it even correct to call the Enlightenment European? Learning Objectives: Upon successful completion of this course, students should be able to • Read texts more critically and effectively • Identify and summarize ideas in texts in an articulate and persuasive manner, verbally and in writing • Display a grasp of the key methodological questions involved in “globalizing” the Enlightenment • Display a grasp of some the key concepts that can be used to illustrate the global perspective of European eighteenth century thinkers. Requirements: • Regular class participation demonstrating careful reading of all assigned texts: 30% • 2-4 sentence summaries of the argument(s) of each of the weekly readings. -

Zimmermann's Forest Formula, Infrared Divergences and the QCD
Zimmermann's Forest Formula, Infrared Divergences and the QCD Beta Function Franz Herzog Nikhef Theory Group, Science Park 105, 1098 XG Amsterdam, The Netherlands Abstract We review Zimmermann's forest formula, which solves Bogoliubov's recur- sive R-operation for the subtraction of ultraviolet divergences in perturba- tive Quantum Field Theory. We further discuss a generalisation of the R- operation which subtracts besides ultraviolet also Euclidean infrared diver- gences. This generalisation, which goes under the name of the R∗-operation, can be used efficiently to compute renormalisation constants. We will discuss several results obtained by this method with focus on the QCD beta function at five loops as well as the application to hadronic Higgs boson decay rates at N4LO. This article summarizes a talk given at the Wolfhart Zimmermann Memorial Symposium. Keywords: Renormalization Group, QCD Email address: [email protected] (Franz Herzog) arXiv:1711.06121v1 [hep-ph] 16 Nov 2017 Preprint submitted to Nuclear Physics B November 17, 2017 1. Introduction Despite the enormous success in describing the interactions of elementary particles the appearance of ultraviolet (UV) divergences make it difficult to establish Quantum Field Theory as a fundamental theory of nature. A solution which at least grants the interpretation of Quantum Field Theories as low energy effective theories is given by the procedure of renormalisation. This is the procedure to absorb the troublesome infinities, present at small distances, into the physical parameters of the theory. An important development in the establishment of renormalisation the- ory has been the Bogoliubov-Parasiuk-Hepp-Zimmermann (BPHZ) renor- malisation scheme. This scheme was originally developed by Bogoliubov and Parasiuk [1] in terms of a recursive subtraction operation, often called Bo- goliubov's R-operation. -
From Department Chair Donald Rutherford
Philosophy * COMMEMORATIVE NEWSLETTER in honor of UC San Diego’s 50th Anniversary SPRING 2011 Welcome from Department Chair Donald Rutherford This special edition of the UCSD Philosophy Newsletter commemorates the department’s 50th Anniversary Symposium, “Philosophy: Then and Now,” held on campus on April 16, 2011. The event was attended by over a hun- dred past and present members and friends of the department. The morning began with talks by emeritus professor Paul Churchland and current faculty member Dick Arneson. After a break for lunch, we continued with a presen- tation by former UCSD colleague, Wayne Martin, visiting from the University of Essex, and a roundtable discussion involving two emeritus and two current faculty members: Avrum Stroll (a founding member of the department), Henry Allison, Georgios Anagnostopoulos, and Jerry Doppelt. Those who attended, I think, were struck by the richness of the department’s tradition of research and teaching in philosophy and the remarkable people who have made it their academic home. In the following pages, you will find many photos from the event, April 16, 2011 Symposium as well as two feature articles: Monte Johnson’s history of the department, “From Historical to Eliminative Materialism (via German Idealism),” and Cath- UC San Diego Philosophy: erine Asmann’s reminiscences of her almost 30-year tenure as a member of Then and Now the departmental staff.

The success of our April symposium has raised the possibility of future events that will unite the department more closely view the Symposium Video with its alumni and members of the community. -
Henry De Monfreid (1879-1974) Solveig Conrad-Boucher Diplômée D'histoire De L'art Et De Lettres Modernes
Henry de Monfreid (1879-1974) Solveig Conrad-Boucher Diplômée d'Histoire de l'art et de Lettres modernes Entré dans la légende comme l'un des derniers aventuriers des temps modernes, Henry de Monfreid succomba à l'appel du large à l'âge de 32 ans. Las de mener “la vie d'un monsieur quelconque de nos cités modernes”, déjà père de famille et avec de nombreux métiers à son actif, il donne un tour radicalement nouveau à son existence en s'embarquant seul en 1911 en direction de Djibouti. Loin du “carcan occidental”, il se soustrait alors définitivement à “l'obligation de la vie en troupeau”, et entame pour les trente années à venir une véritable épopée, le menant à l'intérieur des terres de la corne d'Afrique, mais aussi aux bords de la Mer Rouge et du golfe d'Aden, en passant par la Grèce, l'Inde, les Seychelles et plus tard encore, après son emprisonnement par les Anglais, le Kenya. Tour à tour négociant en peaux et en café, trafiquant d'armes, de perles et de haschisch, Henry de Monfreid “aime surtout aller vers l'inconnu”. Marin d'exception et avide d'horizons nouveaux, il finit par bâtir lui-même ses boutres mythiques destinés au commerce légal comme à la contrebande. Contrairement à ses rivaux, il n'en confie pas le commandement à des autochtones, mais prend lui-même la mer et règne en maître sur son équipage fasciné par cet homme blanc converti à l'Islam, sous le nom de Abd el-Haï, “l'esclave du vivant”.
