Class numbers of binary quadratic polynomials

Zichen Yang

In this paper, we give a formula for the proper class number of a binary quadratic polynomial assuming that the conductor ideal is sufficiently divisible at dyadic places. This all…

Local densities of quadratic polynomials over non-dyadic fields and unramified dyadic fields

Zilong He, Zichen Yang

In this paper, we prove formulas for local densities of quadratic polynomials over non-dyadic fields and over unramified dyadic fields.

The bias conjecture for elliptic curves over finite fields and Hurwitz class numbers in arithmetic progressions

Ben Kane, Sudhir Pujahari, Zichen Yang

In this paper, we consider a version of the bias conjecture for second moments in the setting of elliptic curves over finite fields whose trace of Frobenius lies in an arbitrary fi…
