Analysis Seminar

Tuesday and Thursday 2:00-3:00 pm.
368 Little Hall

Thursday 24 May.

  • Speaker: Michael Jury.
  • Title: The maximum modulus of a random polynomial.
  • Abstract: Flip a fair coin N times, and let ek be +1 if the kth flip was heads, and -1 if it was tails. Form the random polynomial
      sum ek zk
    The maximum modulus of such a random polynomial on the unit circle is then a random variable M. Simple estimates show that
      sqrt{N} leq M leq N
    surely. A theorem of Salem and Zygmund shows that there is a constant C so that with high probability,
      M \leq C \sqrt{N \log N}.
    for all N sufficiently large. I will discuss this theorem and its extension to several variables (due to Kahane).
