Chinese remainder theorem in number theory
WebThis makes the name "Chinese Remainder Theorem'' seem a little more appropriate. The Chinese Remainder Theorem is a useful tool in number theory (we'll use it in section 3.8), and also has proved useful in the study and development of modern cryptographic systems. Exercises 3.7. Ex 3.7.1 Construct the correspondences between the indicated sets. WebThe Chinese Remainder Theorem, X We record our observations from the last slide, which allow us to decompose Z=mZ as a direct product when m is composite. Corollary (Chinese Remainder Theorem for Z) If m is a positive integer with prime factorization m = pa1 1 p a2 2 p n n, then Z=mZ ˘=(Z=pa1 1 Z) (Z=p Z).
