DANSK MATEMATISK FORENING MAT-NYT CALENDAR This document is a hard copy of all entries in the electronic Mat-Nyt calendar of the Danish Mathematical Society covering the period 2004-1-1 – 2004-2-1. Produced Thu Jan 5, 2006 1 MAT-NYT The Danish National Research Foundation Network in Mathematical Physics and Stochastics Mathematical Physics Seminar A Hamiltonian model for linear friction Stephan de Bievre, Villeneuve d’Ascq, France Mon Jan 19 2004, 14:15 - 15:15 Abstract I will present a Hamiltonian model of a particle coupled to a suitable wave field, describing the particle’s environment, in which a simple version of Ohm’s law is valid. When an external force is applied, the particle reaches asymptotically a constant speed proportional to the applied field. I will review the related literature, compare this phenomenon to the one of radiative dissipation, and indicate some of the many open problems Organized by MPS Editor 2004-01-16 13:44:36 ( [email protected] / [email protected] ) 2 MAT-NYT INSTITUT FOR MATEMATISKE FAG MATEMATISK AFDELING KØBENHAVNS UNIVERSITET ALGEBRA SEMINAR The Inverse problem in Gr¨obner basis theory Amelia Taylor, Assistant Professor, St. Olaf College USA Mon Jan 19 2004, 15:15 Abstract Given an ideal in a polynomial ring its initial ideal is easy to compute and is well studied using Gr¨obner basis theory. However, given a monomial ideal what can we say about the types of ideals it is the initial ideal for, that is do we know anything about the inverse problem for Gr¨obner basis theory? This question as stated is currently considered to be too broad, however progress has been made in determining when a monomial ideal is the initial ideal of a prime ideal and in most of the known cases we can we construct the prime ideal. -
Oxfordcolleges
Oxford colleges Oxford University is made up of different colleges. Colleges are academic communities. They are where students usually have their tutorials. Each one has its own dining hall, bar, common room and library, and lots of college groups and societies. If you study here you will be a member of a college, and probably have your tutorials in that college. You will also be a member of the wider University, with access to University and department facilities like laboratories and libraries, as well as hundreds of University groups and societies. You would usually have your lectures and any lab work in your department, with other students from across the University. There is something to be said for an academic atmosphere wherein everyone you meet is both passionate about what they are studying and phenomenally clever to boot. Ziad 144| Does it matter which college I go to? What is a JCR? No. Colleges have a lot more in common than Junior Common Room, or JCR, means two they have differences.

The term Can I choose my college? JCR also refers to all the undergraduates in a college. The JCR elects a committee which Yes, you can express a preference.
