We refute an often invoked theorem which claims that a periodic orbit with an odd number of real Floquet multipliers greater than unity can never be stabilized by time-delayed feedback control in theâ€¦ (More)

We investigate the normal form of a subcritical Hopf bifurcation subjected to time-delayed feedback control. Bifurcation diagrams which cover time-dependent states as well are obtained by analyticalâ€¦ (More)

A variety of methods have been developed in nonlinear science to stabilize unstable periodic orbits (UPOs) and control chaos [1], following the seminal work by Ott, Grebogi and Yorke [2], whoâ€¦ (More)

We consider convex symmetric lens-shaped networks in R that evolve under curve shortening flow. We show that the enclosed convex domain shrinks to a point in finite time. Furthermore, afterâ€¦ (More)

Particle identification at high multiplicities is a key feature of the COMPASS experiment at CERN's SPS. Hadrons up to 50 GeV/c are identified by a RICH detector with a large horizontal and verticalâ€¦ (More)

We consider convex symmetric lens-shaped networks in R 2 that evolve under curve shortening flow. We show that the enclosed convex domain shrinks to a point in finite time. Furthermore, afterâ€¦ (More)
