Breaking the continuity of a piecewise linear map

Viktor AvrutinMichael SchanzBjörn Schenke — 2012

ESAIM: Proceedings

Knowledge about the behavior of discontinuous piecewise-linear maps is important for a wide range of applications. An efficient way to investigate the bifurcation structure in 2D parameter spaces of such maps is to detect specific codimension-2 bifurcation points, called organizing centers, and to describe the bifurcation structure in their neighborhood. In this work, we present the organizing centers in the 1D discontinuous piecewise-linear map...

Unstable Orbits and Milnor Attractors in the Discontinuous Flat Top Tent Map

Viktor AvrutinBen FutterLaura GardiniMichael Schanz — 2012

ESAIM: Proceedings

In this work we consider the discontinuous flat top tent map which represents an example for discontinuous piecewise-smooth maps, whereby the system function is constant on some interval. Such maps show several characteristics caused by this constant value which are still insufficiently investigated. In this work we demonstrate that in the discontinuous flat top tent map every unstable periodic orbit may become a Milnor attractor. Moreover, it turns...

Organizing centers in parameter space of discontinuous 1D maps. The case of increasing/decreasing branches

Laura GardiniViktor AvrutinMichael SchanzAlbert GranadosIryna Sushko — 2012

ESAIM: Proceedings

This work contributes to classify the dynamic behaviors of piecewise smooth systems in which characterize the qualitative changes in the dynamics. A central point of our investigation is the intersection of two border collision bifurcation curves in a parameter plane. This problem is also associated with the continuity breaking in a fixed point of a piecewise smooth map. We will relax the hypothesis needed in [4] where it was proved that in the case...
