2. Free algebra - Wikipedia

   en.wikipedia.org/wiki/Free_algebra

   Over a field, the free algebra on n indeterminates can be constructed as the tensor algebra on an n-dimensional vector space. For a more general coefficient ring, the same construction works if we take the free module on n generators. The construction of the free algebra on E is functorial in nature and satisfies an appropriate universal property.

   en.wikipedia.org/wiki/List_of_algebras

   This is a list of possibly nonassociative algebras.An algebra is a module, wherein you can also multiply two module elements. (The multiplication in the module is compatible with multiplication-by-scalars from the base ring).

6. Free object - Wikipedia

   en.wikipedia.org/wiki/Free_object

   In mathematics, the idea of a free object is one of the basic concepts of abstract algebra.Informally, a free object over a set A can be thought of as being a "generic" algebraic structure over A: the only equations that hold between elements of the free object are those that follow from the defining axioms of the algebraic structure.

7. Basis (universal algebra) - Wikipedia

   en.wikipedia.org/wiki/Basis_(universal_algebra)

   In universal algebra, a basis is a structure inside of some (universal) algebras, which are called free algebras.It generates all algebra elements from its own elements by the algebra operations in an independent manner.
