Salem Constants

Each point of the Pisot-Vijayaraghavan Constants is a Limit Point from both sides of a set known as theSalem constants (Salem 1945). The Salem constants are algebraic Integers in which one or more of theconjugates is on the Unit Circle with the others inside (Le Lionnais 1983, p. 150). The smallest known Salem numberwas found by Lehmer (1933) as the largest Real Root of
