Algebraic relations among periods and logarithms of rank 2 Drinfeld modules
Chieh-Yu Chang, Matthew A. Papanikolas
For any rank 2 Drinfeld module rho defined over an algebraic function field, we consider its period matrix P, which is analogous to the period matrix of an elliptic curve defined o…

Frobenius difference equations and algebraic independence of zeta values in positive equal characteristic
Chieh-Yu Chang, Matthew A. Papanikolas, Jing Yu
In analogy with the Riemann zeta function at positive integers, for each finite field F_p^r with fixed characteristic p we consider Carlitz zeta values zeta_r(n) at positive intege…
