Since then the goal has been to show that for each fixed ϵ > 0 {\displaystyle \epsilon >0} there exists a real number C ( ϵ ) {\displaystyle C(\epsilon )} such that E ( r ) ≤ C ( ϵ ) r 1 / 2 + ϵ {\displaystyle E(r)\leq C(\epsilon )r^{1/2+\epsilon }} .
Dende entón o obxectivo foi demostrar que para cada ϵ > 0 {\displaystyle \epsilon >0} fixo existe un número real C ( ϵ ) {\displaystyle C(\epsilon )} tal que E ( r ) ≤ C ( ϵ ) r 1 / 2 + ϵ {\displaystyle E(r)\leq C(\epsilon )r^{1/2+\epsilon }} .
