A. Markov’s inequality was the first ever inequality proved for derivatives of polynomials: given a polynomial of a particular degree and a bound on its maximum on an interval, it provides the sharp estimate on the maximum of its derivative on that interval. A. Markov proved it to answer a question posed by D. Mendeleev regarding alcohol measurements. We briefly present that story.

摘要

A. Markov’s inequality was the first ever inequality proved for derivatives of polynomials: given a polynomial of a particular degree and a bound on its maximum on an interval, it provides the sharp estimate on the maximum of its derivative on that interval. A. Markov proved it to answer a question posed by D. Mendeleev regarding alcohol measurements. We briefly present that story.
