The great theorem of A.A. Markoff and Jean Bernoulli sequences

A proof of Markoff’s Great Theorem on the Lagrange spectrum using continued fractions is sketched. Markoff’s periods and Jean Bernoulli sequence 11Following Markoff [A.A. Markoff, Sur une question de Jean Bernoulli, Math. Ann. 19 (1882), 27–36] we assume that Johann(III) Bernoulli = Jean Bernoulli. sed to obtain a simple algorithm for the computation of the Lagrange spectrum below 3.
