Algebra over a field

An algebra over a field is a Vector space over equipped with a bilinear product , #m/def/ralg i.e. for any and

This may be generalized to an -algebra.

Examples

• -monoid¹
  • Commutative
    • Complex number
    • Quaternion (non-commutative)
    • Symmetric algebra
  • Non-commutative
    • Matrix algebra over a field
    • Endomorphism ring
    • Tensor algebra
    • Clifford algebra
    • Monoid ring
    • Extension field as a unital associative algebra
• Category ring
• Non-associative
  • Lie algebra

Properties

• The product within an algebra is completely determined by its Structure constants
