Abstract:

The continued fractions that are the subject of this paper display a particular kind of "self-similar" structure: that is, their partial quotients are created by manipulating and moving the denominators of their convergents. An alternating series characterizes the real numbers that these continued fractions represent. Using an application of Roth's theorem, we prove the transcendence of these numbers.
