摘要 For low degree systems (n≤3), it is verified that all convex combination of a (s) and b(s) keeping Hurwitzness is a necessary and sufficient condition for the existence of c(s) such that both c(s)/a(s) and c(s)/b(s) are SPR. For low degree systems (n?3), it is verified that all convex combination ofa (s) andb (s) keeping Hurwitzness is a necessary and sufficient condition for the existence ofc (s) such that bothc(s)/a(s) andc(s)/b(s) are SPR.
