An explicit lifting construction of CAP forms on O(1,5)
Hiro-aki Narita, Ameya Pitale, Siddhesh Wagh
We explicitly construct non-tempered cusp forms on the orthogonal group O(1,5) of signature (1+,5-). Given a definite quaternion algebra B over , the orthogonal group i…

Maass space for lifting to GL(2) over a division quaternion algebra
Siddhesh Wagh
Muto, Narita and Pitale construct counterexamples to the Generalized Ramanujan Conjecture for GL(2,B) over the division quaternion algebra B with discriminant two via a lift from S…
