Robust Oscillation Analysis for a Family of Polynomials
Wensheng Yu · Acta Scicentiarum Naturalum Universitis Pekinesis · 1997
The robust oscillation for some polynomials' families is discussed.A vertex verification result for the robust oscillation of polytopic polynomial family,under some conditions,is obtained.Moreover,the number of vertex polynomial to be checked can be reduced for interval polynomial family and diamond polynomial family.A counter example is given to show that these vertex verification results cann't be directly generalized for root distribution invariance of polynomial families.
