Abstract
In this paper we investigate the Galois conjugates of a Pisot number , . In particular, we conjecture that for we have for all conjugates of . Further, for , we conjecture that for all Pisot numbers we have . A similar conjecture if made for . We conjecture that all of these bounds are tight. We provide partial supporting evidence for this conjecture. This evidence is both of a theoretical and computational nature. Lastly, we connect this conjecture to a result on the dimension of Bernoulli convolutions parameterized by , whose conjugate is the reciprocal of a Pisot number.
