CHINREM

Type: CoiTUTiand

Description: Solves a system of simultaneous polynomial

congruences in the ring Z[x].

Access: Arithmetic, R1(MTR] polynomial

Input: Level 2/Argiunent 1: A vector of the first congruence

(expression and modulus).

Level 1/Argument 2: A vector of the second congruence

(expression and modulus).

Output: A vector of the solution congruence (expression and

modulus).

Flags: Exact mode must be set (flag -105 clear).

Numeric mode must not be set (flag -03 clear).

Example: Solve the followurg simultaneous congruences for the

polynomial u:

u=x +1 (moda:+2)

u = .x~~ ] (mod x+3)

Command: CHINREM{ [X^2 + l,X+2] , [X-l,X+3] )

Result: [X"3+2*X''2 + 5 , - (X"2 + 5*X+6) ]
