Special semester on Motivic Homotopy Theory.

The Research group Levine is holding a special semester in motivic homotopy theory during the Summer semester 2014, with the financial support of the Alexander von Humboldt Foundation. In addition to the residence of numerous guest researchers during the semester, several lecture series and a Workshop in motivic homotopy groups of spheres form part of the program. For further information about the activities planned for the special semester as well as a list of the researchers in residence, please see the website.

DFG Priority Programme on Homotopy theory and Algebraic Geometry

In its March 2014 meeting, the Senate of the DFG approved the establishment of a Special Programm in homotopy theory and algebraic geometry. Coordinator of this Programm is Prof. Dr. Marc Levine; additional Initiators are Prof. Dr. Hélène Esnault (FU Berlin), Prof. Dr. Birgit Richter (Univ. Hamburg) und Prof. Dr. Stefan Schwede (Univ. Bonn). The main goal of the Programm is to stimulate the interactions between the areas of homotopy theory and algebraic geometry via projects in research areas such as motivic homotopy theory, derived algebraic geometry as related to ring spectra, equivariant homotopy theory, differential homotopy theory and the application of ideas and methods of homotopy theory to algebraic geometry. A number of conferences and workshops on these topics are planned.

ESAGA joins the ALGANT consortium

The Essen seminar has joined the ALGANT consortium. The consortium offers a two-year world-class integrated master course and a joint doctorate program in pure mathematics, with a strong emphasis on Algebra, Geometry and Number Theory. Both programs have received the Erasmus Mundus label.

Workshop: Riemann-Roch for Deligne-Mumford stacks

The traditional workshop Essen-Paderborn will take place on January 19+20 in Essen. We will study a version of the Riemann-Roch theorem for Deligne-Mumford stacks, due to Edidin, Graham and others.


We welcome the new post-docs, PhD students and guests, who joined the Essen Seminar for Algebraic Geometry and Arithmetic this semester: Federico Binda (Univ. Milan), Jin Cao (Chinese Academy of Sciences, Beijing), Viet-Cuong Do (Nancy), Jean Fasel (LMU München), Christian Haesemeyer (UCLA), Yong Hu (Univ Paris-Sud 11), Shane Kelly (Univ. Paris 13), Kelvin Liu (Michigan State Univ.), Oleg Podkopaev (Norwestern Univ.), Shu Sasaki (King’s College London), Haifeng Wu (Capital Normal Univ. Beijing).

Hélène Esnault accepts offer from FU Berlin

Hélène Esnault has accepted a chair at the Freie Universität Berlin starting October 1st, 2012, taking up the first Einstein-professorship of the FU Berlin.

For over twenty years Hélène Esnault, together with her husband Eckart Viehweg, has significantly contributed to the development of mathematics in Essen, especially in the field of algebraic geometry. In 2003 Hélène Esnault and Eckart Viehweg received the Leibniz Award of the German Science Foundation, giving further impetus to their formation of a large and active research group whose influence has been felt far beyond Essen, and establishing the foundation for the present Essen Seminar for Algebraic Geometry and Arithmetic.
We wish Hélène Esnault all the best for her future in Berlin and for our part hope that a solid connection with Essen will remain. The succession for the Chair Esnault is expected be announced in the course of the coming weeks.

Eckart Viehweg (Dez. 1948 – Jan. 2010)

Eckart Viehweg was university professor for mathematics in Essen from 1984 through 2010, initially at the Gesamthochschule Essen, and after the fusion Essen/Duisburg at the University of Duisburg-Essen. During this time – and from 1990 on together with Hélène Esnault – he was dedicated to the advancement of algebraic geometry in Essen, and played a significant part in the development of the faculty of mathematics.

His scientific achievements were honoured by numerous awards and distinctions. He was invited speaker at the International Congress of Mathematicians in Berkeley in 1986. In the year 2009 he was elected to the Deutsche Akademie der Naturforscher Leopoldina. In the same year he was awarded honorary doctorate of the Vietnam Academy of Science and Technology in Hanoi.

The Leibniz Award of the German Science Foundation which he received together with his wife, Hélène Esnault, in 2003 made it possible to greatly expand the activities of the research team. With this and other subsequent projects Essen grew to be a highly active site for algebraic geometry, with numerous connections to the worldwide mathematical community. It is these personal contacts – to mathematicians in leading nations such as the US and France as well as to those in scientifically less developed countries – that were always of great importance to Eckart Viehweg.
