Abstract:

Given the Eigenvalue problem A - lambda Ex 0 for a real or complex matrix A, the number of Eigenvalues lambda with positive real parts is determined without evaluating the characteristic polynomial. A procedure is developed to transform the given matrix A to a canonical form by means of a finite series of elementary transformations of the matrix. The elements of the reduced matrix allow one to solve immediately the stability problem. Author
