Prime Values of Elliptic Divisibility Sequences If u denotes the n-th term of an EDS then u grows very quickly. In fact log|u | ~ cn2. Chudnovsky and Chudnovsky considered some EDSs specified by writing down their first five terms and examined these sequences for prime terms. Since u is a divisibility sequence, which grows so quickly, it is sufficient to examine prime occurence of terms u with n ...
