Nettet24. okt. 2008 · In this paper a direct proof of the Routh-Hurwitz conditions themselves is given using Liapunov's second method. The new proof is ‘elementary’ in that it depends on the fundamental concept of stability associated with Liapunov's second method, and not on theorems in the complex integral calculus which are required in the usual proofs. Let f(z) be a complex polynomial. The process is as follows: 1. Compute the polynomials and such that where y is a real number. 2. Compute the Sylvester matrix associated to and . 3. Rearrange each row in such a way that an odd row and the following one have the same number of leading zeros.
