Abstract

Let Bn(t) be a n-th Stern polynomial and let e(n)=\opdegBn(t) be its degree. In this note we continue our study started in \citeUl of the arithmetic properties of the sequence of Stern polynomials and the sequence \e(n)\n=1. We also study the sequence d(n)=\opordt=0Bn(t). Among other things we prove that d(n)=ν(n), where ν(n) is the maximal power of 2 which dividies the number n. We also count the number of the solutions of the equations e(m)=i and e(m)-d(m)=i in the interval [1,2n]. We also obtain an interesting closed expression for a certain sum involving Stern polynomials.
