On sup-norm bounds part I: ramified Maa{\ss} newforms over number fields

Number Theory 2017-10-03 v1

Abstract

We prove new upper bounds for the sup-norm of Hecke Maa{\ss} newforms on GL(2)GL(2) over a number field. Our newforms are more general than those considered in a recent paper by Blomer, Harcos, Maga, and Mili\`cevi\`c: we do not require square free level. Furthermore, we allow for non-trivial central character. Over the rationals we cover the best bounds as obtained by Saha.
