| Abstract: | In this note we will characterize all non-arithmetic ternary quadratic forms with unbounded multiplicities. It turns out that their existence is closely related with certain classes of elliptic curves whose investigation is interesting on its own. Received March 3, 1997; in final form November 13, 1997 |
