%0 Journal Article %T A two parameter family of piecewise linear transformations with negative slope %A F. Hofbauer %J ACTA MATHEMATICA UNIVERSITATIS COMENIANAE %D 2012 %I Acta Mathematica Universitatis Comenianae %X We study a two parameter family of piecewise linear transformations on the interval [0, 1] which have negative slope. We show that the nonwandering set consists of finitely many periodic orbits and an invariant set L which is topologically transitive and the disjoint union of finitely many closed intervals. We determine the number of these intervals. %K Piecewise linear map %K nonwandering set. %U http://www.emis.de/journals/AMUC/_vol-81/_no_1/_hofbauer/hofbauer.html
