Rational-function extension of the static approximate Gauss–Lucas conjecture
Rational-function extension of the static approximate Gauss–Lucas conjecture
Let be convex, and let be given. There exists some constant for which the following holds. Let be rational functions, and assume that all zeros, poles, and critical points of lie in . Rational-function extension conjecture. If
then
This extends the preceding static principle to an unbounded convex set and rational functions, assuming that the zeros, poles, and critical points of already lie in . The supplied text presents it as an additional conjecture and gives no resolution.
