Remarks on Periods of Planar Hamiltonian Systems
Autor: Franz Rothe
Publikováno v: SIAM Journal on Mathematical Analysis. 24:129-154
Criteria for monotonicity of the periods of planar Hamiltonian systems from various authors are logically related. From the more restrictive criteria, not only monotonicity is proved, but even a further convexity property of the energy-period functio

Multiple bifurcation in a predator–prey system with nonmonotonic predator response
Autor: Franz Rothe, Douglas S. Shafer
Publikováno v: Proceedings of the Royal Society of Edinburgh: Section A Mathematics. 120:313-347
SynopsisA model of a predator–prey system showing group defence on the part of the prey is formulated, and reduced to a three-parameter family of quartic polynomial systems of equations. Mathematically, this system contains the Volterra–Lotka sys

An analogue to the Smale—Birkhoff homoclinic theorem for iterated entire mappings
Autor: Franz Rothe
Publikováno v: Aequationes Mathematicae. 47:328-328
A snapback repeller of an analytic mapping is defined as a full orbit which tends to an unstable fixed point backwards in time and snaps back to the same fixed point. This note gives a rather elementary proof that unstable periodic orbits accumulate
