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. -
The Dorothy Hodgkin Symposium
The Principal and Fellows of Somerville College, Oxford together with UNESCO and the International Union of Crystallography request the pleasure of your company at The Dorothy Hodgkin Symposium Celebrating the 50th Anniversary of the award of Dorothy Hodgkin’s Nobel Prize in Chemistry and the International Year of Crystallography Wednesday 29th October 2014 You are warmly invited to attend a one-day symposium that aims to recognise Dorothy Hodgkin’s legacy and mark the award of her Nobel Prize. Her field, crystallography, underpins all of the sciences today and has an extensive range of applications within the agro-food, aeronautic, computer, electro-mechanical, pharmaceutical and mining industries and more. 45 scientists have been awarded the Nobel Prize over the past century for work that is either directly or indirectly related to crystallography, and yet it remains a field relatively unknown to the general public. This year UNESCO has joined forces with the International Union of Crystallography to promote education and public awareness, and we are delighted to contribute to this effort with the Dorothy Hodgkin Symposium. PROGRAMME 2:45 pm Tea & Coffee, Somerville College, Flora Anderson Hall 3:00 pm Hidden Glory, Dorothy Hodgkin in her own words, Somerville College, Flora Anderson Hall A filmed performance of a short, one-woman play about the life and work of Dorothy Hodgkin, followed by Q&A with the playwright Georgina Ferry 4:00 pm Registration, Mathematical Institute, University of Oxford 4:10 pm Welcome, Mathematical Institute, -

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 Magazine for Alumni and Friends of Durham University
THE MAGAZINE FOR ALUMNI AND FRIENDS OF DURHAM UNIVERSITY 2018 ISSUE 04 ISSUE 04 2018 DUNELM MAGAZINE 3 Dear alumni of Durham Durham, as it always has, is continuing to develop. Major advances have been made on the plans laid out in the University Strategy, 2017-2027. As you will see in your magazine, we have begun work on a new Centre for Teaching and Learning near St Mary’s and we now have planning permission for our 17th college, the first in ten years, which will be built near Van Mildert on South Road. The developments at Maiden Castle and in Computer Science are also moving forward quickly. You can see the artists’ drawings of some of these projects over the next few pages. In order to prepare the way for the transition of colleges and departments into Durham from Queen’s Campus Stockton, Ustinov College has now moved into a first-class new home at Sheraton Park (the old Neville’s Cross college site), and John Snow and Stephenson Colleges have established bases in Durham City in preparation for their move into Durham over the summer. Meanwhile in Queen’s, our new International Study Centre (ISC) has enjoyed a successful first term, and we are looking forward to a large number of ISC students joining Durham University degree courses next year. All of this work is designed not only to keep Durham at the pinnacle of UK education but also to expand our global reputation and reach; and so I am also pleased to let you know that we have a new Pro-Vice-Chancellor, Professor Claire O’Malley, who will lead on globalizing Durham. -
