Unitary Spaces on Clifford Algebras

- N. Marchuk, D. Shirokov
- Mathematics, Physics
- 11 May 2007

Abstract.For the complex Clifford algebra (p, q) of dimension n = p + q we define a Hermitian scalar product. This scalar product depends on the signature (p, q) of Clifford algebra. So, we arrive at… Expand

Concepts of trace, determinant and inverse of Clifford algebra elements

- D. Shirokov
- Mathematics, Physics
- 27 August 2011

In our paper we consider the notion of determinant of Clifford algebra elements. We present some new formulas for determinant of Clifford algebra elements for the cases of dimension 4 and 5. Also we… Expand
