Chinese remainder theorem abstract algebra
In mathematics, the Chinese remainder theorem states that if one knows the remainders of the Euclidean division of an integer n by several integers, then one can determine uniquely the remainder of the division of n by the product of these integers, under the condition that the divisors are … See more The earliest known statement of the theorem, as a problem with specific numbers, appears in the 3rd-century book Sun-tzu Suan-ching by the Chinese mathematician Sun-tzu: There are certain … See more Let n1, ..., nk be integers greater than 1, which are often called moduli or divisors. Let us denote by N the product of the ni. The Chinese remainder theorem asserts that if the ni are pairwise coprime, and if a1, ..., ak are integers such that 0 ≤ ai < ni for every i, then … See more Consider a system of congruences: $${\displaystyle {\begin{aligned}x&\equiv a_{1}{\pmod {n_{1}}}\\&\vdots \\x&\equiv a_{k}{\pmod {n_{k}}},\\\end{aligned}}}$$ where the $${\displaystyle n_{i}}$$ are pairwise coprime, and let See more The statement in terms of remainders given in § Theorem statement cannot be generalized to any principal ideal domain, but its … See more The existence and the uniqueness of the solution may be proven independently. However, the first proof of existence, given below, uses this uniqueness. Uniqueness Suppose that x and y are both solutions to all the … See more In § Statement, the Chinese remainder theorem has been stated in three different ways: in terms of remainders, of congruences, and of a ring isomorphism. The statement in terms of remainders does not apply, in general, to principal ideal domains, … See more The Chinese remainder theorem can be generalized to any ring, by using coprime ideals (also called comaximal ideals). Two ideals I … See more WebNov 21, 2024 · $\begingroup$ I wouldn't call this the general Chinese Remainder Theorem. The general CRT is stated for an arbitrary commutative ring and coprime ideals (and your version directly follows from it), hence you should be able to find it in any book on general abstract algebra. Off top of my head, there is a short proof in the first chapter in …
