 Clifford algebra

For a vector space with quadratic form $Q$, its Clifford algebra is generated by vectors subject to $v^2=Q(v)1$. In a basis this is equivalently ${\gamma }^{\mu }{\gamma }^{\nu }+{\gamma }^{\nu }{\gamma }^{\mu }=2{\eta }^{\mu \nu }1$.

Clifford algebra is a mathematical structure that extends the concept of vector spaces and inner products into a more generalized algebraic framework. It is named after the mathematician William Kingdon Clifford, who developed the concept in the 19th century. ### Definition A Clifford algebra is generated from a vector space \( V \) equipped with a quadratic form.
