The T-Graph of a Multigraded Hilbert Scheme
[OWP-2011-34] (Mathematisches Forschungsinstitut Oberwolfach, 2011)The T-graph of a multigraded Hilbert scheme records the zero and one-dimensional orbits of the T=(K∗)n action on the Hilbert scheme induced from the T-action on An. It has vertices the T-fixed points, ... -
Upper bounds for the number of solutions to quartic thue equations
[OWP-2011-21] (Mathematisches Forschungsinstitut Oberwolfach, 2011)We will give upper bounds for the number of integral solutions to quartic Thue equations. Our main tool here is a logarithmic curve ϕ(x,y) that allows us to use the theory of linear forms in logarithms. This manuscript ... -
The Weyl group of the Cuntz algebra
[OWP-2011-31] (Mathematisches Forschungsinstitut Oberwolfach, 2011-05-28)The Weyl group of the Cuntz algebra On is investigated. This is (isomorphic to) the group of polynomial automorphisms λu of On, namely those induced by unitaries u that can be written ...
