A characterization of isochronous centres in terms of symmetries

, 2004
We present a description of isochronous centres of planar vector fields X by means of their groups of symmetries. More precisely, given a normalizer U of X (i.e., [X,U]= µ X, where µ is a scalar function), we provide a necessary and sufficient ...

First derivative of the period function with applications [PDF]

, 2001
Given a centre of a planar differential system, we extend the use of the Lie bracket to the determination of the monotonicity character of the period function.

Regularity properties of the period function near a centre of a planar vector field

, 1992
We study the problem of analytic extension up to the singular point of the period function of a centre of a planar analytic vector field, and discuss condition of ...

CTF3: Design of Driving Beam Combiner Ring [PDF]

, 2001
In CTF3 the beam compression of the driving beam structure between the main linac and the decelerating section is obtained with a delay loop and a combiner ring which increase the pulse current by a factor 10. The design of the combiner ring is presented.
