Abstract: In this talk we discuss recent results on optimal quantitative weak approximation for certain projective quadrics over the rational numbers as well as quantitative results on strong approximation for quaternary quadratic forms over the integers. We will also discuss how a Brauer-Manin obstruction can affect the growth of coprime integer points of bounded height on a quaternary quadratic form. This is joint work with Zhizhong Huang and Alec Shute.
