The integer transfinite diameter of intervals and totally real algebraic integers

V. Flammang, G. Rhin, C. J. Smyth (1997)

Journal de théorie des nombres de Bordeaux

Similarity:

In this paper we build on some recent work of Amoroso, and Borwein and Erdélyi to derive upper and lower estimates for the integer transfinite diameter of small intervals [ r s , r s + δ ] , where r s is a fixed rational and δ 0 . We also study functions g - , g , g + associated with transfinite diameters of Farey intervals. Then we consider certain polynomials, which we call polynomials, associated to a given interval I . We show how to estimate from below the proportion of roots of an integer polynomial which is sufficiently...
