Category:Residue Classes

This category contains results about Residue Classes.
Definitions specific to this category can be found in Definitions/Residue Classes.

Let $\RR_m$ be the congruence relation modulo $m$ on the set of all $a, b \in \Z$:

$\RR_m = \set {\tuple {a, b} \in \Z \times \Z: \exists k \in \Z: a = b + k m}$

So for any $m \in \Z$, we denote the equivalence class of any $a \in \Z$ by $\eqclass a m$, such that:

$\ds \eqclass a m$

$=$

$\ds \set {x \in \Z: a \equiv x \pmod m}$

$\ds $

$=$

$\ds \set {x \in \Z: \exists k \in \Z: x = a + k m}$

$\ds $

$=$

$\ds \set {\ldots, a - 2 m, a - m, a, a + m, a + 2 m, \ldots}$

The equivalence class $\eqclass a m$ is called the residue class of $a$ (modulo $m$).
