The sum of these values for an n x n ["n by n"] matrix is equal to the (*) trace.
The kth symmetric function of these quantities is defined as the sum of their products taken k at a time. These mathematical entities must possess negative real parts according to one condition of Lyapunov's first theorem. The dimension of the subspace A matrix is invertible if and only if these values do not equal zero. The sum of these values for an n x n ["n by n"] matrix is equal to the (*) trace. These values, which are only defined for square matrices, are usually written as lambda in an equation that finds the roots of a characteristic polynomial. For a triangular matrix, these values are found on the matrix's main diagonal. For 10 points, name these special scalars in mathematics, which are used to find eigenvectors.
