Let be a zero of a polynomial of degree with odd coefficients, with not a root of unity. We show that the height of satisfiesMore generally, we obtain bounds when the coefficients are all congruent to modulo for some .
We prove formulas for the k-higher Mahler measure of a family of rational functions with an arbitrary number of variables. Our formulas reveal relations with multiple polylogarithms evaluated at certain roots of unity.
We consider a certain class of polynomials whose zeros are, all with one exception, close to the closed unit disk. We demonstrate that the Mahler measure can be employed to prove irreducibility of these polynomials over ℚ.
We prove that every cyclic cubic extension of the field of rational numbers contains algebraic numbers which are Mahler measures but not the Mahler measures of algebraic numbers lying in . This extends the result of Schinzel who proved the same statement for every real quadratic field . A corresponding conjecture is made for an arbitrary non-totally complex field and some numerical examples are given. We also show that every natural power of a Mahler measure is a Mahler measure.
