Circularity in finite fields and solutions of the equations \(x^m + y^m - z^m = 1\). (English) Zbl 07905714
Summary: An explicit formula for the number of solutions of the equation in the title is given when a certain condition, depending only on the exponent and the characteristic of the field, holds. This formula improves the one given by the authors in an earlier paper.
