      The design of gridshell structures is a complicated process, as the resulting shape of structure depends on initial undeformed grid geometry as well as on the history of boundary conditions used to form the final structure. ...

    • ITINERARIES INDUCED BY EXCHANGE OF THREE INTERVALS 

      Autor: Masáková , Zuzana; Pelantová , Edita; Starosta , Štěpán
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      We focus on a generalization of the three gap theorem well known in the framework of exchange of two intervals. For the case of three intervals, our main result provides an analogue of this result implying that there are ...

    • ITINERARIES INDUCED BY EXCHANGE OF TWO INTERVALS 

      Autor: Masáková , Zuzana; Pelantová , Edita
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
      We focus on the exchange T of two intervals with an irrational slope α. For a general subinterval I of the domain of T, the first return time to I takes three values. We describe the structure of the set of return itineraries ...
