NT&AG: Damaris Schindler (Utrecht University), "Systems of quadratic forms"

Mon, 21/11/201614:00-15:00
Ros Building, 70A
In this talk we discuss some aspects concerning the arithmetic of
systems of quadratic forms. This includes a result on the frequency of
counterexamples to the Hasse principle for del Pezzo surfaces of degree
four (joint work with J. Jahnel), and a result on the representability of
integers by systems of three quadratic forms (joint work with L. B. Pierce
and M. M. Wood).
