stock return is usually considered to be affected by firm’s financial ratios as well as economic variables. fundamental method assume that stock returns is not solely related to the stock market. most result come from the company condition , industry situation and whole economy. in this paper, this relationship between stock return and fundamentals is studied using the data for 22 pharmaceutica...

this paper takes fundamental analysis research beyond the spatial and temporal bounds of previous studies. it was investigated that how detailed financial statement data enter the decisions of market makers by examining how current changes in the fundamental signals chosen can provide information on subsequent earnings changes. using tehran stock exchange’s firms data from 2003 to 2012, the rol...

We present a mathematical theory of the two-dimensional offset curves from the viewpoint of medial axis transform. We explore the local geometry of the offset curve in relation with the medial axis transform, culminating in the classification of points on the offset curve. We then study the domain decomposition from the viewpoint of offsets, and in particular introduce the concept of monotonic ...

The viscous shallow water equations and quasi-geostrophic equations are considered in this paper. Some new terms, related to the Coriolis force, are revealed thanks to a rigorous asymptotic analysis. After providing well-posedness arguments for the new models, the authors perform some numerical computations that confirm the role played by the cosine effect in various physical configurations.

Abstract. We consider half–infinite triangular Toeplitz matrices with slow decay of the elements and prove under a monotonicity condition that the elements of the inverse matrix, as well as the elements of the fundamental matrix, decay to zero. We provide a quantitative description of the decay of the fundamental matrix in terms of p–norms. The results add to the classical results of Jaffard an...
