Joint Mathematics Meetings January 13-16, 2010 26 | MAA FOCUS | October/November 2009 Join Us in San Francisco, CA Joint Mathematics Meetings January 13-16, 2010 Dear Colleagues, he 2010 Joint Mathematics Meetings in San Francisco Tpromises to be an exciting gathering. It comes on the heels of MathFest in Portland and the Joint Meetings in Washing- ton, DC that each set a record for the highest attendance ever. The MAA invited speakers will be Manjul Bhargava, Lenore Blum, David Kung, Glen Van Brummelen, Dusa McDuff, and Sue Whitesides. Cliff Stoll will give the student MAA presenta- tion. Joseph Harris and Brian White are the joint MAA-AMS speakers, and this year we will get to hear Steven Strogatz give the first MAA-AMS-SIAM public lecture, which was post- poned from last year. The San Francisco meeting will again feature the AMS invited lectures, the popular Mathematical Art Exhibit, the Undergraduate Poster Session (which last year drew almost 300 presenters), and the heavily-attended Graduate School Fair for undergraduates. The six MAA Invited Paper Sessions include one on Environmental Mathematics and one on the Mathematics of Origami, with Erik Demaine and Robert Lang among the speakers. Tom Banchoff and Jacqueline Dewar will host a joint MAA-AMS Invited Paper Session on the Scholarship of Teaching and Learning in Mathematics. There will be lots of interesting mathematics as well as opportunities to learn new things, meet new people, see old friends, and have a great time. Please join the festivities. I look forward to seeing you in San Francisco. David Bressoud MAA President Photograph by Jerry Lee Hayes for the San Francisco Convention Bureau.

  • 1 Lenore Blum, Matemática Computacional, Algoritmos, Lógica, Geometría Algebraica
    MATEMATICOS ACTUALES Lenore Blum, Matemática computacional, Algoritmos, Lógica, Geometría algebraica. Debemos dejar claro desde el comienzo de esta biografía de Lenore Blum que Blum es su apellido de casada, que solo tomó después de casarse con Manuel Blum, que también era matemático. Sin embargo, para evitar confusiones, nos referiremos a ella como Blum a lo largo de este artículo. Los padres de Lenore eran Irving y Rose y, además de una hermana, Harriet, que era dos años menor que Lenore, ella era parte de una extensa familia judía con varias tías y tíos. Su madre Rose era maestra de ciencias de secundaria en Nueva York. Lenore asistió a una escuela pública en la ciudad de Nueva York hasta que tuvo nueve años cuando su familia se mudó a América del Sur. Su padre Irving trabajaba en el negocio de importación/exportación y él y su esposa se instalaron en Venezuela con Lenore y Harriet. Durante su primer año en Caracas, Lenore no asistió a la escuela, sin embargo su madre le enseñó. Básicamente, la familia era demasiado pobre para poder pagar las tasas escolares. Al cabo de un año, Rose ocupó un puesto docente en la Escuela Americana E. Campo Alegre, en Caracas, y esto proporcionó suficiente dinero para permitir que Lenore asistiera a la escuela secundaria y luego a la escuela secundaria en Caracas. Mientras estaba en Caracas, conoció a Manuel Blum, quien también era de una familia judía. Manuel salió de Caracas mientras Lenore todavía estaba allí en la escuela y se fue a los Estados Unidos donde ingresó como estudiante en el Instituto de Tecnología de Massachusetts.

    CRonEM CRonEM HHMC 2017 (2017 Workshop on Hybrid Human-Machine Computing) 20 & 21 September 2017 Treetops, Wates House, University of Surrey Guildford, Surrey, UK Programme INTRODUCTION KEYNOTE 1 The 2017 Workshop on Hybrid Human-Machine Computing (HHMC 2017) is 2-day workshop, to be held Title: Password Generation, an Example of Human Computation at the University of Surrey, Guildford, UK, on 20 and 21 September, 2017. It is a workshop co-funded by Abstract: University of Surrey’s Institute for Advanced Studies (IAS), a number of other organizations and related research projects. A password schema is an algorithm for humans - working in their heads - without paper and pencil - to transform challenges (typically website names) into responses (passwords). When we talk about “computing” we often mean computers do something (for humans), but due to the more and more blurred boundary between humans and computers, this old paradigm of “computing” has To start this talk, the speaker will ask for 2 or 3 volunteers, whisper instructions in their ears, then have them changed drastically, e.g., in human computation humans do all or part of the computing (for machines), transform audience-proposed challenges (like AMAZON and FACEBOOK) into passwords. in computer-supported cooperative work (CSCW) humans are working together with assistance from The passwords will look random. The audience will be challenged to guess properties of the passwords but computers to conduct cooperative work, in social computing and computer-mediated communication even the simple schema the speaker whispered to the volunteers will produce passwords that look random. people’s social behaviors are intermingled with computer systems so computing happens with humans and These passwords can be easily made so strong that they pass virtually all password tests, like passwordmeter.

  • Mathematisches Forschungsinstitut Oberwolfach Reflection Positivity
    Mathematisches Forschungsinstitut Oberwolfach Report No. 55/2017 DOI: 10.4171/OWR/2017/55 Reflection Positivity Organised by Arthur Jaffe, Harvard Karl-Hermann Neeb, Erlangen Gestur Olafsson, Baton Rouge Benjamin Schlein, Z¨urich 26 November – 2 December 2017 Abstract. The main theme of the workshop was reflection positivity and its occurences in various areas of mathematics and physics, such as Representa- tion Theory, Quantum Field Theory, Noncommutative Geometry, Dynamical Systems, Analysis and Statistical Mechanics. Accordingly, the program was intrinsically interdisciplinary and included talks covering different aspects of reflection positivity. Mathematics Subject Classification (2010): 17B10, 22E65, 22E70, 81T08. Introduction by the Organisers The workshop on Reflection Positivity was organized by Arthur Jaffe (Cambridge, MA), Karl-Hermann Neeb (Erlangen), Gestur Olafsson´ (Baton Rouge) and Ben- jamin Schlein (Z¨urich) during the week November 27 to December 1, 2017. The meeting was attended by 53 participants from all over the world. It was organized around 24 lectures each of 50 minutes duration representing major recent advances or introducing to a specific aspect or application of reflection positivity. The meeting was exciting and highly successful. The quality of the lectures was outstanding. The exceptional atmosphere of the Oberwolfach Institute provided the optimal environment for bringing people from different areas together and to create an atmosphere of scientific interaction and cross-fertilization. In particular, people from different subcommunities exchanged ideas and this lead to new col- laborations that will probably stimulate progress in unexpected directions. 3264 Oberwolfach Report 55/2017 Reflection positivity (RP) emerged in the early 1970s in the work of Osterwalder and Schrader as one of their axioms for constructive quantum field theory ensuring the equivalence of their euclidean setup with Wightman fields.

In 1989, Mike Shub, Steve Smale, and I introduced In this article, I discuss these results and indi- a theory of computation and complexity over an cate how basic notions from numerical analysis arbitrary ring or field R [BSS89]. If R is such as condition, round-off, and approximation are Z2 = ({0, 1}, +, ·), the classical computer science being introduced into complexity theory, bringing theory is recovered. If R is the field of real num- together ideas germinating from the real calculus bers R, Newton’s algorithm, the paradigm algo- of Newton and the discrete computation of com- rithm of numerical analysis, fits naturally into our puter science. The canonical reference for this ma- model of computation. terial is the book Complexity and Real Computation Complexity classes P, NP and the fundamental [BCSS98].
