# Continued Fractions-Book Supplements and Errata

- Page 113, line -6, $|\sum_1^n s_j{\bf b}_j|\ge |{\bf b}_d|$ (reverse direction of inequality)
- Page 141, line 4, on the RHS, multiply by $\rho({\bf c})$.
- Page 228, exp[z]=1+2z/(2-z+z^2/(6+z^2/(10+z^2/(14+...)))). (There is no (2+z^2 before the 6+z^2).
- Page 171, LHS of first display should read G-G_N, not G-G_n.
- The Hermite continued fraction Hermite algorithm Mathematica notebook .
- The Lagarias geodesic multidimensional continued fraction Mathematica notebook algorithm implemented in Mathematica. A version compatible with Mathematica 6.* .
- Another proof of the theorem of Stern and Stolz; conceptually quite simple, computationally a bit of a pain absent computer algebra.
- Jerry Lange's converse Mathematica notebook to the theorem of Stern and Stolz.
- Mathematica notebook concerning the Zaremba conjecture to the effect that for all n there exists k such that the continued fraction expansion of k/n involves only partial quotients no greater than 5. Also treats the possibility that for sufficiently large n, 5 can be replaced by 2.
- Note that Bourgain and Kontorovich have recently obtained a strong result in the direction of the Zaremba conjecture: there exists an (explicit, reasonably small e.g. 3000) positive integer q such that for almost all n, there exists k such that the continued fraction expansion of k/n involves only partial quotients less than q.
- The analogue of the Gauss density for the Hurwitz complex continued fraction algorithm.
- Notebook documenting computations related to the growth rate of Abs[q_n] in the Hurwitz complex continued fraction algorithm.

- This was held Monday April April 21. Here are solutions: Freshman Version solutions , and Sophomore version solutions. Some of the problems were common to both versions. Winners were Siying Peng, Kenneth Taliaferro, William Sames, Louis Tronzo, and Luiz Faria, respectively first, second, third, and tied for 4th-5th.
- Freshman-Sophomore Contest 2007: This was held Monday April 30. Here are solutions to both the first-year and second-year versions: Freshman Version Solutions, Sophomore Version Solutions. The first three problems were common to both versions. Winners were: First place, Gleb Zhelezov. Second place, Zack Darwin and Karthic Gopavaram (tie). Fourth place, Joseph Stratton. Fifth place, Shyam S. Kumar. Sixth place, Luiz Faria and Kenneth Taliaferro (tie).

# Texas A&M Freshman-Sophomore Math Contest results.

- For contest purposes, freshman means anyone who is in their first year of post-highschool studies, and sophomore, anyone in their second year. Those 9 hours of AP History you got don't push you over into Junior status, in other words.
- Problems and solutions Y2K. Freshman and sophomore contestants had the same problems in common for the first page, but the second page problems were different. this link gives the solutions to the common problems and to the second page's freshman problems. Sophomore problem solutions to questions 4, 5, and 6 will be posted shortly. (And here they are.
