Mean square in the prime geodesic theorem

Giacomo Cherubini and João Guerreiro

Vol. 12 (2018), No. 3, 571–597

We prove upper bounds for the mean square of the remainder in the prime geodesic theorem, for every cofinite Fuchsian group, which improve on average on the best known pointwise bounds. The proof relies on the Selberg trace formula. For the modular group we prove a refined upper bound by using the Kuznetsov trace formula.
