Determinant of block matrices

Web1 1 Introduction The determinant is one of the basic parameters in matrix theory. The determinant of a square matrix A = (ai,j ) ∈ Cn×n is defined as X n Y det(A) = sgn(σ) ai,σ(i) , σ∈Sn i=1 where the symbol Sn denotes the group of permutations of sets with n elements and the symbol sgn(σ) denotes the signature of σ ∈ Sn . WebJan 1, 2024 · Let M be an m n × m n matrix over a commutative ring R.Divide M into m × m blocks. Assume that the blocks commute pairwise. Consider the following two procedures: (1) Evaluate the n × n determinant formula at these blocks to obtain an m × m matrix, and take the determinant again to obtain an element of R; (2) Take the m n × m n …
