Restriction Estimates and Applications to Number Theory


Heilbronn Number Theory Seminar


14th October 2026, 4:00 pm – 5:00 pm
Fry Building, 2.04


In this talk, I will introduce restriction estimates and discuss their applications to additive problems in number theory. I will focus on two examples. The first concerns a quadratic Waring–Goldbach problem with variables restricted to short intervals, based on joint work with Lilu Zhao. The second concerns a version of Vinogradov’s theorem involving Piatetski–Shapiro primes, based on joint work with Shanshan Du and Hao Pan.
