Abstract
An explicit construction of a reduced hyperbolic integer operator from the group SL(2, ℤ) such that one of the periods of the corresponding geometric continued fraction in the sense of Klein coincides with a given sequence of positive integers is presented. An algorithm determining periods for any operator in SL(2, ℤ) (which is based on Gauss’ reduction theory) is experimentally studied.
