A note on quantitative stability in Hilbert spaces

Yifan Jing

We study stability theory in Hilbert spaces quantitatively. We prove that the inner product on the unit ball is $(k, ε)$ -stable for all $k \geq exp (π / ε)$ , and it is not $(k, ε)$ -stabl…

Semialgebraic methods and generalized sum-product phenomena

Yifan Jing, Souktik Roy, Chieu-Minh Tran

For a bivariate $P (x, y) \in R [x, y] ∖ (R [x] \cup R [y])$ , our first result shows that for all finite $A \subseteq R$ , $|P(A,A)|\geq α|A|^{5…
