On three-variable expanders over finite valuation rings

Nguyen Van The, Phuc D Tran, Le Quang Ham +1

Let $R$ be a finite valuation ring of order $q^{r}$ . In this paper, we prove that for any quadratic polynomial $f (x, y, z) \in R [x, y, z]$ that is of the form $axy+R(…

Some sum-product type estimates for two-variables over prime fields

Phuc D Tran, Nguyen Van The

In this paper, we use a recent method given by Rudnev, Shakan, and Shkredov (2018) to improve results on sum-product type problems due to Pham and Mojarrad (2018).
