Determinant of a matrix to a power

WebFor a square matrix 𝐴 and positive integer π‘˜, we define the power of a matrix by repeating matrix multiplication; for example, 𝐴 = 𝐴 Γ— 𝐴 Γ— β‹― Γ— 𝐴, where there are π‘˜ copies of matrix 𝐴 on the right-hand side. It is important to recognize that the power of a matrix is only well defined if the matrix is a square matrix. WebIf 𝑀 is a square matrix of order 𝑛 by 𝑛 and π‘˜ is any scalar value, then the determinant of π‘˜ times 𝑀 is equal to π‘˜ to the 𝑛th power multiplied by the determinant of 𝑀. In other words, we can take scalar multiplication outside of our calculation of the determinant.

WebConsider an m n Γ— m n matrix over a commutative ring A, divided into n Γ— n blocks that commute pairwise. One can pretend that each of the m 2 blocks is a number and apply the m Γ— m determinant formula to get a single block, and then take the n Γ— n determinant to get an element of A. Or one can take the big m n Γ— m n determinant all at once.
