Kathy O ' Hara ' s Constructive Proof of the Unimodality of the Gaussian Polynomials

  title={Kathy O ' Hara ' s Constructive Proof of the Unimodality of the Gaussian Polynomials},

Once written, I thought that it would be nice if all the readers of this Monthly had the opportunity to savor this elegant proof. All the central ideas and constructions are O’Hara’s, but I have made a few minor improvements and shortcuts that I believe to make the argument clearer. I would like to… CONTINUE READING
