First moment of Rankin–Selberg central L-values and subconvexity in the level aspect
Let 1≤ N < M with N and M coprime and square-free. Through classical analytic methods we estimate the first moment of central L -values where runs over primitive holomorphic forms of level N and trivial nebentypus and g is a given form of level M . As a result, we recover the bound when g is dihe...

Zusammenfassung: | Let 1≤
N
<
M
with
N
and
M
coprime and square-free. Through classical analytic methods we estimate the first moment of central
L
-values
where
runs over primitive holomorphic forms of level
N
and trivial nebentypus and
g
is a given form of level
M
. As a result, we recover the bound
when
g
is dihedral. The first moment method also applies to the special derivative
under the assumption that it is non-negative for all
