Contracting orbits in Outer space
We show that strongly contracting geodesics in Outer space project to parameterized quasigeodesics in the free factor complex. This result provides a converse to a theorem of Bestvina– Feighn, and is used to give conditions for when a subgroup of Out(F) has a quasi-isometric orbit map into the free factor complex. It also allows one to construct many new examples of strongly contracting geodesi...
متن کاملPeriodic Orbits in Outer Billiard
It is shown that the set of 4-period orbits in outer billiard with piecewise smooth convex boundary has an empty interior, provided the boundary is not a parallelogram.
متن کاملResearch Announcement: Unbounded Orbits for Outer Billiards
In [S] we proved that the outer billiards system defined on the Penrose kite has an unbounded orbit. In this article we will sketch some of the main ideas in the proof, and describe in detail a very convincing computer demonstration of our result.
متن کاملPlants circling in outer space
Plants do not grow in a strict linear manner, rather they circumnutate. That is, they exhibit an oscillatory or helical growth pattern around an axis. Circumnutation is readily apparent in vines such as morning glory or grape (Fig. 1), but in fact it is nearly ubiquitous in plants. Circumnutation occurs in almost all plant organs throughout all stages of development (Johnsson, 1997; Larson, 200...
