## The basic element method (BEM) for **decomposition of an algebraic polynomial via basic elements** (one cubic and three parabolas) is developed within the four-point transformation technique. This gives a lever at solving various tasks of applied mathematics. So, in the **polynomial approximation** and **smoothing problems** the BEM presentation allows one to **reduce the computational complexity of the algorithms and to increase their stability to errors** by choice of the internal relationship structure between variable and control parameters. ## The basic element method (BEM) for **decomposition of an algebraic polynomial via basic elements** (one cubic and three parabolas) is developed within the four-point transformation technique.

**There are three main levels within the Grid-environment: network, resource and applied. **
** The network level deals with high-speed backbones and telecommunication links. **
** The resource level consists of high-performance computing clusters, and data storage systems joined in a unified Grid and cloud environment with the help of basic software and middleware. **
** The applied level involves research topics the solutions of which have been adapted to the Grid&cloud environment in frames of corresponding virtual organizations. **
