Abstract: Abstract We consider a single degree freedom oscillator in order to accurately represent some modelling with ship roll damping. The proposed oscillator is a nonsmooth Rayleigh-Duffing equation x + a x + b x |… read more here.

Abstract: In the paper we deal with a quintic Liénard system of the form ẋ=y−(a1x+a2x3+a3x5),ẏ=b1x+b2x3 with a Z2 -symmetry, where a1,a2,b1∈R and a 3 b 2 ≠ 0. A complete study of this system with b… read more here.
