[Case II] det (Adj (A)) = nonzero, so Adj (A) is invertible. Let (Adj (A))^ {-1} =B. From A Adj (A)=det (A)I, A Adj (A) B= det (A)I B. Suppose that det (A)=0. Then A = 0. So Adj A =0 implies det (Adj A)=0, a contradiction. Therefore det (A) = nonzero.

In linear algebra, the adjugate or classical adjoint of a square matrix A is the transpose of its cofactor matrix and is denoted by adj(A). It is also occasionally known as adjunct matrix, or "adjoint", though the latter term today normally refers to a different concept, the adjoint operator which for a matrix is the conjugate transpose. The product of a matrix with its adjugate gives a diagonal matrix (entries not on the main diagona… WebI thought that that isn't much of a trick or shortcut; it seems about the same complexity as just plodding through row/column operations to convert the 3x3 into an identity matrix and applying those operations to an identity matrix at the same time. Of course, if there's an expectation that the determinant is 1, then maybe it's appropriate.

WebApr 10, 2024 · In the Heisenberg picture the entire time dependence is in the self-adjoint operators that describe observables, and the statistical operator (or for pure states the state vector) is constant.
