#### An application of the Abel **equation** of first type to the task of solving the Friedman **equations**

... field and the special form of Abel **equation** of the first kind is presented. In particular, it is shown how, knowing the general solution of the Abel **equation** (corresponding to the given scalar field potential) one can obtain the general solution of the **Friedmann** **Equation**.

#### Finite action principle and non-singular cosmological models

... form an extremely narrow subclass and look quite unnatural. However, our goal is to show that such cosmologies are possible in principle without conflicting with current physical paradigms.
