Toroidal families and averages of $L$-functions, II: cubic moments

Étienne Fouvry, Emmanuel Kowalski, Philippe Michel +1

Generalizing our previous work on ``toroidal averages'', we study the average of special values of $L$-functions of the form $L(1/2,{\chi }^a)L(1/2,{\chi }^b)L(1/2,{\chi }^c)$ for integers $a$, $b$…
