摘要
Explicit expressions for all the 3n + 2 primitive idempotents in the ring R-pnq = GF(l)[x]/(x(pnq) - 1), where p, q, l are distinct odd primes, l is a primitive root modulo p(n) and q both, gcd(phi(p(n))/2, phi(q)/2) = 1, are obtained. The dimension, generating polynomials and the minimum distance of the minimal cyclic codes of length p(n)q over GF(l) are also discussed. (C) 2003 Elsevier Science (USA). All rights reserved.
