Scientific paper
In the paper algebraic decomposition of the Einstein tensor is used as a tool for solving Einstein equation. Analytical expressions for metric tensors of the general families of spherically-symmetric static space-times, filled by a static scalar field or by an oscillating complex scalar field (bosonic stars), were found by this technique. It is shown that in the case of minimal coupling such space-times is uniquely determined by one or two characteristic functions.
