Teaching 20152016

Here are
slides, etc., of some of my talks
(BMC 2001, BMC 2002, Dagstuhl 2004, Banff 2005, Belfast 2007, VU 2007, Utrecht 2009,...).


Research Information
My work is concentrated around algebraic Ktheory, especially in the direction
of Zagier's, Goncharov's and Beilinson's conjectures. It
involves making Kgroups more explicit, computing regulators and
establishing relations between those regulators and the values of Lfunctions
at certain points.
Since this area relates to and uses techniques from
number theory and arithmetic algebraic geometry, I also do research
in those fields without any link to algebraic Ktheory. As some of my work is computer
based there are also algorithmic aspects to my research.
I was the scientist in charge of the Durham node in the EC network
Arithmetic Algebraic Geometry that ended
31st January 2008.
I was also associated with the Edinburgh node in the EC network
Algebraic KTheory, Linear Algebraic Groups and Related Structures,
which finished 30th September 2006.
Nowadays I take part in the
The Netherlands Organisation for Scientific Research (NWO)
cluster
DIAMANT.
Sander Dahmen also works in my research group.
Through the Arithmetic Algebraic Geometry network, or through other sources of money, I had various postdocs:
JeanGuillaume Grebet, Niklas Broberg,
Ivan Horozov,
Daniel Caro,
Tejaswi Navilarekallu and
Marco Streng.
At the moment
Deepam Patel is on a postdoc
position funded by a 3year NWO grant, with an interruption for one year for a
fellowship at the IHES.
Currently I have two PhD students,
Bogdan Banu and François Escriva.
Hang Liu, a PhD student at the Graduate University of the Chinese Academy of Sciences,
started a 2year visit in January 2013.
Events
We have an
algebra seminar.
There were also some earlier
algebra events
(with algebra interpreted rather broadly), in particular in the context of
DIAMANT
and the
Intercity Number Theory seminar.
From time to time I have some
visitors.
With some other people I organized a
Stieltjes "onderwijsweek"
in January 2010, where the topics were inspired by
the
lectures of Spencer Bloch
as Stieltjes professor hosted by me in February and March 2010.
Together with Pedro Luis del Angel, Javier Elizondo, James Lewis, Paulo
LimaFilho and Deepam Patel I organize a workshop on
cohomological realizations of motives in December 2014 in Banff.
Earlier I organized
