SpletThen I will describe how the adjoint twisted Reidemeister torsion shows up in the asymptotic expansion of the invariants. Especially, we find new explicit formulas for the adjoint twisted Reidemeister torsion of the fundamental shadow link complements and of the 3-manifolds obtained by doing hyperbolic Dehn-filling on those link complements. SpletThe trace of any matrix A, Tr(A) is defined as the sum of its diagonal elements. Some properties of trace of matrices are, tr(AB) = tr(BA) ... Step 3: Find the adjoint matrix by … SpletAn adjoint matrix is also called an adjugate matrix. In other words, we can say that matrix A is another matrix formed by replacing each element of the current matrix by its corresponding cofactor and then taking the transpose of the new matrix formed. Suppose, then Adj A = Example 1: Consider the matrix Find the Adj of A. subways and railroads in saudi arabia
