摘要：
Let p be an odd prime, and let m be a positive integer satisfying p(m) = 3(mod 4). Let F-pm be the finite field with pm elements, and let R = F-pm [u]/< u(2)> be the finite commutative chain ring with unity. In this paper, we determine all constacyclic codes of length 4p(s) over R and their dual codes, where s is a positive integer. We also determine their sizes and list some isodual constacyclic codes of length 4p(s) over R.
