## Approximate solutions by truncated Taylor series expansions of nonlinear differential equations and related shadowing property with applications.(English)Zbl 1474.34077

Summary: This paper investigates the errors of the solutions as well as the shadowing property of a class of nonlinear differential equations which possess unique solutions on a certain interval for any admissible initial condition. The class of differential equations is assumed to be approximated by well-posed truncated Taylor series expansions up to a certain order obtained about certain, in general nonperiodic, sampling points $$t_i \in [t_0, t_J]$$ for $$i = 0,1, \ldots, J$$ of the solution. Two examples are provided.
