This study aimed to analyze the structure of the banking industry and the level of competition of banking institutions in Indonesia. In measuring and analyzing the model used Panzar-Rosse built on indicators of competition, called H-Stats, which provide a quantitative assessment of the competitive nature of the market. H-statistics calculated from equation reduction in revenue and the size of the total revenue elasticity with respect to changes in input factor prices. Panzar and Rosse show that with certain assumptions, comparison of the static nature of the type of the equation provides a replacement for the overall level of competition prevailing in the market. By using secondary data issued by Bank Indonesia (BI), this study used pooled the data (data panel) is to combine data from year 2010 to 2014 on 9 banking institutions. The results showed that the level of competition in the Indonesian banking industry generally contain the elements of nature and the nature of the market monopoly of perfect competition or are in a situation of monopolistic competition (monopolistic competitions)

In this paper we deal with an approximative analytical solution of a second order differential equation with a fast time periodic modulation. We use for this type of the equation a homotopy perturbation method. The validity of this approximative solution is verified by numerical experiments, where we achieve considerable consistency of doth soliutions.

The cosmological behavior is investigated for ten-dimensional scalar–tensor theory with matter. The matter is taken as an anisotropic fluid. As a simple ansatz, the anisotropic fluid for each four and six dimensions satisfies the same type of the equation of state with different coefficients, px,y = γx,yρ. Following the ansatz of the anisotropic matter, the spacetime then has a product structure which means that the spacetime is decomposed as four-dimensional spacetime (Mx) and six-dimensional transverse space (My). We focus on the solution such that the scale factors in each four and six dimensions behave differently. The corresponding cosmological solutions are obtained for general γx,y. By giving specific numeric values for the coefficients of the equation of state γx,y, we find the solution which behaves in such a way that the spatial three dimensions are expanding while the extra six dimensions are contracting.

In this paper, we are interested in the mathematical analysis of a geological stratigraphic model, taking into account a limited weathering condition. Firstly, we present the physical model and the mathematical formulation, which lead to an original locally hyperbolic conservation law. Then, after some heuristic simplifications, the definition of a solution and some mathematical tools in order to resolve the problem are given. Within the framework of sedimentation processes, we illustrate in the 1-D case the changing type of the equation: hyperbolic with finite speed propagation and parabolic with diffusive comportment or stationary. At the end, we present some open problems related to free boundary phenomena.
