The paper deals with stiff systems of differential equations. To solve this sort of system numerically is a diffcult task. In spite of the fact that we come across stiff systems quite often in the common practice, a very interesting and promising numerical method of solving systems of ordinary differential equations (ODE) based on Taylor series has appeared ("Modern Taylor Series Method" (MTSM)).
The potential of the Taylor series has been exposed by many practical experiments and a way of detection and explicit solution of large systems of ODE has been found. Detailed analysis of stability and convergence of explicit and implicit Taylor series is presented and the algorithm using implicit Taylor series - based on recurrent calculation of Taylor series terms and Newton iteration method (ITMRN) is described.
