Positivity Conditions for Quartic Polynomials
1990) Positivity Conditions for Quartic Polynomials. Technical Report TR-90-57, Computer Science, Virginia Polytechnic Institute and State University. (
Simple necessary and sufficient conditions that a quartic polynomial f(z) be non-negative for z greater than or equal to 0 or a is less than or equal to z and z is less than or equal to b are derived, and illustrated geometrically. The geometry provides considerable insight and suggests various approximations and computational simplifications. The theory is applied to monotone quintic spline interpolations, giving necessary and sufficient conditions and an algorithm for monotone Hermite quintic interpolation.
