ONLY ONE MADE THE GRADE. What good is an online homework system if it can’t recognize right from wrong? Our sentiments exactly. Which is why we decided to compare WebAssign with the other leading homework system for math. The results were surprising. The other system failed to recognize correct answers to free response questions time and time again. That means students who were actually answering correctly were receiving failing grades. WebAssign, on the other hand, was designed to recognize and accept more iterations of a correct answer. In other words, WebAssign grades a lot more like a living, breathing professor and a lot less like, well, that other system. So, for those of you who thought that other system was the right answer for math, we respectfully say, “Sorry, that’s not correct.” 800.955.8275 webassign.net/math WA ad Notices.indd 1 10/1/10 11:57:36 AM QUANTITATIVE FINANCE RENAISSANCE TECHNOLOGIES, a quantitatively based financial management firm, has openings for research and programming positions at its Long Island, NY research center.

Ferrara - CERN, 2016 1 Supergravity as carved on the Iconic Wall at the «Simons Center for Geometry and Physics», Stony Brook S. Ferrara - CERN, 2016 2 Prelude S. Ferrara - CERN, 2016 3 In the early 1970s I was a staff member at the Frascati National Laboratories of CNEN (then the National Nuclear Energy Agency), and with my colleagues Aurelio Grillo and Giorgio Parisi we were investigating, under the leadership of Raoul Gatto (later Professor at the University of Geneva) the consequences of the application of “Conformal Invariance” to Quantum Field Theory (QFT), stimulated by the ongoing Experiments at SLAC where an unexpected Bjorken Scaling was observed in inclusive electron- proton Cross sections, which was suggesting a larger space-time symmetry in processes dominated by short distance physics. In parallel with Alexander Polyakov, at the time in the Soviet Union, we formulated in those days Conformal invariant Operator Product Expansions (OPE) and proposed the “Conformal Bootstrap” as a non-perturbative approach to QFT. S. Ferrara - CERN, 2016 4 Conformal Invariance, OPEs and Conformal Bootstrap has become again a fashionable subject in recent times, because of the introduction of efficient new methods to solve the “Bootstrap Equations” (Riccardo Rattazzi, Slava Rychkov, Erik Tonni, Alessandro Vichi), and mostly because of their role in the AdS/CFT correspondence. The latter, pioneered by Juan Maldacena, Edward Witten, Steve Gubser, Igor Klebanov and Polyakov, can be regarded, to some extent, as one of the great legacies of higher dimensional Supergravity.

Chelsea is pursuing a minor in Jewish Studies in addition to a major in International Affairs and a certificate in Digital Arts and Media. She first joined the Program in Jewish Studies because she wanted to incorporate genocide and religious studies into her broader major, and was specifically attracted to learning about gendered experiences within both the Holocaust and Judaism. We would like to congratulate Chelsea on recently being awarded the 2014 Jacob Van Ek S cholar Award! An outstanding student, this past year, Chelsea has also received the Wrenn Scholarship from the Boulder Chapter of the United Nations Association and the Ripple Award from the Dennis Small Cultural Center. During her time at CU, Chelsea has served as a member of the Jewish Studies Student Advisory Board, was the co-president of Hillel, played for CU's Women's Rugby team, served on CUSG and Student Outreach Retention Center for Equity (SORCE), and was on the KVCU Radio 1190 Task Force. Chelsea also works for the CU Recreation Center. This past summer 2013, Chelsea completed the CU in D.C. summer session, interning with Women's Action for New Directions and the Women Legislators' Lobby in Washington, DC. She worked particularly on women's advocacy and defense budget issues, as well as nuclear policies.

  • Physics-Compatible Discretization Techniques on Single and Dual Grids, with Application to the Poisson Equation of Volume Forms
    Physics-compatible discretization techniques on single and dual grids, with application to the Poisson equation of volume forms Artur Palhaa, Pedro Pinto Rebelob, Rene´ Hiemstrab, Jasper Kreeftc, Marc Gerritsmab,∗ aDelft University of Technology, Faculty of Aerospace Engineering, Wind Energy Group P.O. Box 5058, 2600 GB Delft, The Netherlands bDelft University of Technology, Faculty of Aerospace Engineering, Aerodynamics Group P.O. Box 5058, 2600 GB Delft, The Netherlands cShell Global Solutions, The Netherlands Abstract This paper introduces the basic concepts for physics-compatible discretization techniques. The paper gives a clear distinction between vectors and forms. Based on the difference between forms and pseudo-forms and the ?-operator which switches between the two, a dual grid description and a single grid description are presented. The dual grid method resembles a staggered finite volume method, whereas the single grid approach shows a strong resemblance with a finite element method. Both approaches are compared for the Poisson equation for volume forms. Keywords: Mimetic discretization, differential forms, single grid, dual grid, geometric flexibility. 1. INTRODUCTION Mimetic methods aim to preserve essential physical/mathematical structures in a discrete setting. Many of such structures are topological, i.e. independent of metric, and involve integral relations. Since integration will play an important role and integration of differential forms is a metric-free operation, we will work with differential forms. Formally, differentials forms are linear functionals on multi-vectors, but Flanders, [17, p.1], refers to them as ‘things which occur under integral signs’. Such would not be the case if we were to use vectors, because integration of vector quantities is a metric operation.

  • On Fields of Totally $ S $-Adic Numbers
    ON FIELDS OF TOTALLY S-ADIC NUMBERS — WITH AN APPENDIX BY FLORIAN POP — LIOR BARY-SOROKER AND ARNO FEHM Abstract. Given a finite set S of places of a number field, we prove that the field of totally S-adic algebraic numbers is not Hilbertian. The field of totally real algebraic numbers Qtr, the field of totally p-adic algebraic numbers Qtp, and, more generally, fields of totally S-adic algebraic numbers QS, where S is a finite set of places of Q, play an important role in number theory and Galois theory, see for example [5, 9, 11, 7]. The objective of this note is to show that none of these fields is Hilbertian (see [3, Chapter 12] for the definition of a Hilbertian field). Although it is immediate that Qtr is not Hilbertian, it is less clear whether the same holds for Qtp. For example, every finite group that occurs as a Galois group over Qtr is generated by involutions (in fact, the converse also holds, see [4]) although over a Hilbertian field all finite abelian groups (for example) occur. In contrast, over Qtp every finite group occurs, see [2]. In fact, although (except in the case of Qtr) it was not clear whether these fields are actually Hilbertian, certain weak forms of Hilbertianity were proven and used, both explicitly and implicitly, for example in [4, 6]. Also, any proper finite extension of any of these fields is actually Hilbertian, see [3, Theorem 13.9.1]. The non-Hilbertianity of Qtp was implicitly stated and proven in [1, Examples 5.2] but this result seems to have escaped the notice of the community and was forgotten.
