Abstract:
In this article is
expounds effective method of low to order, is appears same analog
of algorithm Rauses and is allows to define the number of roots
the previous polynom, is lies so in left, that in right
semi-plane, no more that for ${\frac{5}{4}}n(n+1)$ elementary
arithmetical operations.
Keywords:semi-plane, coefficient, stability,
material roots, absolutes stability and nostability.
