Abstract

We compute the one-level density of zeros of order ℓ Dirichlet L-functions over function fields \mathbbF_q[t] for ℓ=3,4 in the Kummer setting (q≡1\pmodℓ) and for ℓ=3,4,6 in the non-Kummer setting (q\not≡1\pmodℓ). In each case, we obtain a main term predicted by Random Matrix Theory (RMT) and lower order terms not predicted by RMT. We also confirm the symmetry type of the families is unitary, supporting Katz and Sarnak's philosophy.
