Opis

Presenting the proceedings of the conference held in Provo, Utah, this work provides research articles in several different areas of number theory, highlighting the Markoff spectrum. It contains refereed contributions on: problems of diophantine approximation; the modular group and its subgroups; continued fractions; and, hyperbolic geometry.
