Signatures of units and congruences (mod 4) in certain totally real fields.
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 , where is a fixed rational and . We also study functions associated with transfinite diameters of Farey intervals. Then we consider certain polynomials, which we call critical polynomials, associated to a given interval . We show how to estimate from below the proportion of roots of an integer polynomial which is sufficiently...
Let be a totally positive algebraic integer, with the difference between its trace and its degree at most 6. We describe an algorithm for finding all such , and display the resulting list of 1314 values of which the algorithm produces.
