 # GL_2 Ramanujan conjecture exponent
 
 ## Description of constant
-We define $C_{56} = \delta_2$ to be the smallest real number $\delta \ge 0$ such that the following uniform bound toward the Generalized Ramanujan Conjecture holds.

 > (**Hypothesis $H_2(\delta)$, specialization of [BB2011]**) For every number field $F$, every cuspidal automorphic representation $\pi$ of $\mathrm{GL}_2(\mathbb A_F)$ with unitary central character, and every place $v$ of $F$, the local component $\pi_v$ is "$\delta$-tempered".
