Erratum to: Bifurcation analysis of a piecewise-linear impact oscillator with drift

1 Erratum to: Nonlinear Dyn DOI 10.1007/s11071-014-1285-5

The following errors were introduced and/or left unaddressed by Springer during production of the original publication:

In the caption to Fig. 1, concerning part b, the term ‘visco elastic’ should have read ‘visco-elastic’.

Section 3.1 (Basic framework), $3^\mathrm{rd}$ sentence: A superscript ‘T’ should have indicated transpose operation in

“Denote by $u:=(p, y, q, s)^\mathrm{T}\in \, W_g\times {\mathbb {S}}^1$ the state variables of the system...”

In the same section, the jump function given for the No contact $\textit{2} \pi (NC\hbox {-}\textit{2}\pi )$ segment should have read as follows:

$$\begin{aligned} g_{2\pi } (u):=\left( {{\begin{array}{c} p \\ y \\ q \\ {s-2\pi } \\ \end{array} }} \right) . \end{aligned}$$

In addition, Fig. 6 was published without proper axis labels. The correct Fig. 6 is printed below.

Fig. 6

Bifurcation diagram of the drifting oscillator with respect to a. The red curve represents the continuation of the period-1 motion shown in Fig. 2, while the diagram in blue corresponds to the bifurcation picture generated via direct numerical integration. The diagrams were computed for the parameter values $b = 0.15$, $\omega = 0.1$, $\xi = 0.05$, $g = 0.02$ and $\varphi _0 = 0.$ (Color figure online)
