Signatures of hermitian forms and "prime ideals" of Witt groups
Speaker: Dr. Vincent Astier (UCD)
Time: 4.00 PM
Date: Monday 23rd September 2013
Location: Casl Seminar Room Block 8 (Belfield Office Park)
Abstract:
We explain how the classical correspondence between signatures of quadratic forms, prime ideals of the Witt ring and morphisms from the Witt ring into Z can be extended to the case of hermitian forms over a central simple algebra with involution. This is joint work with Thomas Unger (UCD).
