Abstract algebra - Wikipedia
WEBIn mathematics, more specifically algebra, abstract algebra or modern algebra is the study of algebraic structures, which are sets with specific operations acting on their elements. [1] . Algebraic structures include groups, rings, fields, modules, vector spaces, lattices, and algebras over a field.
WEBThe central idea behind abstract algebra is to define a larger class of objects (sets with extra structure), of which Z and Q are definitive members. (Z, +) −→ (Z, +, ×) −→ (Q, +, ×) −→. In linear algebra the analogous idea is.
