Wiktionary:
6. (algebra, ring theory) an abelian group equipped with the operation of multiplication by an element of a ring (or another of certain algebraic objects), representing a generalisation of the concept of vector space with scalar multiplication

omadusi
- vektoreid saab selles liita ja skalaariga korrutada
- liitmise suhtes on Abeli rühm
- skalaarid moodustavad ühikelemendiga ringi
- skalaaride a, b ja vektorite x, y vahel kehtivad seosed:
a(bx) = (ab)x
1x = x
(a + b)x = ax + bx
a(x + y) = ax + ay

näide
iga aditiivne Abeli rühm, kui skalaarideks on täisarvude hulk
