Location: Mathematical Sciences Seminar Room

Let F be a formally real field, A a central simple F-algebra and σ an F-linear involution on A. I will describe how to compute signatures of hermitian forms defined over (A,σ) with respect to orderings on F and address a gap in the literature.
This is joint work with Vincent Astier.
