Rengasteoria

Rengasteoria on algebran osa-alue, jonka tutkimuskohteena ovat renkaat – algebralliset rakenteet, joille on määritelty yhteen- ja kertolasku.

Vaihdannaiset renkaat

Pääartikkelit: Vaihdannainen algebra ja vaihdannainen rengas

Rengasta kutsutaan vaihdannaiseksi, jos sen kertolasku on vaihdannainen. Jos ${\textstyle R}$ on rengas, jossa on määritelty yhteenlasku (${\textstyle +}$) ja kertolasku (${\textstyle \cdot }$), niin ${\textstyle R}$ on vaihdannainen, jos mille tahansa alkioille ${\textstyle a,b\in R}$ pätee $a\cdot b=b\cdot a$. Esimerkkejä vaihdannaisista renkaista ovat polynomirenkaat, algebrallisten kokonaislukujen renkaat samoin kuin tavalliset kokonaisluvut, ja p-aditiset kokonaisluvut.
