Trace and Berezinian of matrices over a Clifford algebra
We define the notions of trace, determinant and, more generally, Berezinian of matrices over a (Z_2)^n-graded commutative associative algebra A.The applications include a new approach to the classical theory of matrices with coefficients in a Clifford algebra, in particular of quaternionic matrices. In a special case, we recover the classical Dieudonne determinant of quaternionic matrices, but in general our quaternionic determinant is different.
