Smoothed Analysis for the Condition Number of Structured Real Polynomial Systems Academic Article uri icon


  • We consider the sensitivity of real zeros of structured polynomial systems to perturbations of their coefficients. In particular, we provide explicit estimates for condition numbers of structured random real polynomial systems, and extend these estimates to the smoothed analysis setting.
