A Generalization of Mordell to Ternary Quadratic Forms
arXiv:1508.02694 · doi:10.1142/S1793042116501256
Abstract
Mordell in 1958 gave a new proof of the three squares theorem. We generalize those techniques to characterize the integers represented by the remaining six "Ramanujan-Dickson ternaries" as well as three other ternary forms.
