In this paper, we examine some basic properties of the multiple-Sine-Gordon (MSG) systems, which constitute a generalization of the celebrated sine-Gordon (SG) system. We start by showing how MSG systems can be viewed as a general class of periodic functions.Next, periodic and step-like solutions of these systems are discussed in some details.In particular, we study the static properties of such systems by considering slope and phase diagrams. We also use concepts like energy density and pressure to characterize and distinguish such solutions. We interpret these solutions as an interacting many body system, in which kinks and antikinks behave as extended particles. Finally, we provide a linear stability analysis of periodic solutions which indicates short wavelength solutions to be stable. PACS: 05.45.Yv, 05.00.00, 02.60.Lj, 24.10.Jv I. INTRODUCTION The double-Sine-Gordon (DSG) equation which is a generalization of the ordinary Sine-Gordon (SG) equation has been the focus of much recent investigations [1-15]. It has been shown to model a variety of systems in condensed matter, quantum optics, and particle physics [2]. Condensed matter applications include the spin dynamics of superfluid 3 He [3, 4], magnetic chains [5], commensurateincommensurate phase transitions [6], surface structural reconstructions [7], and domain walls [8,9] and fluxon dynamics in Josephson junction [10].In quantum field theory and quantum optics, DSG applications include quark confinement [11] and self-induced transparency [12]. The internal dynamics of multiple and single DSG soliton configurations using molecular dynamics have been studied in [2]. There have also been studies about kink anti-kink collision processes for DSG equation [13]. One can also point to the statistical mechanics applications [14], and perturbation theory for this system [15]. Following our pervious study on the periodic and step-like solutions of DSG equation[1], we focus on a generalization of this system with the self-interaction potential (see Fig.1) *
