As part of the ceremony at Aarhus University, May 29 2015 the award winner Signe Agerhom Clausen will present some of her main results from her thesis, "Coinvariant rings and Demazure operators". Her supervisor Henning Haahr Andersen from QGM will illustrate how these Demazure operators have led to surprising applications in recent breakthroughs in representation theory.

The review committee concluded that
Signe Agerholm Clausen's thesis is an excellent contribution to an important topic in algebra. She has studied Demazure operators on covariant rings for Coxeter groups with special emphasis on the case of symmetric groups. Here she has obtained non-trivial generalisations by showing how one may pass from covariant rings over the reals to the corresponding rings over the integers. The thesis is extremely well-written and the basic theory behind her results is thoroughly and clearly explained.

The Prize award ceremony is in Aud. D1 29 May 2015 at 16:15.
