The ordinary differential equation

(Abel's differential equation of the first kind) or

(Abel's differential equation of the second kind). These equations arose in the context of the studies of N.H. Abel [1] on the theory of elliptic functions. Abel's differential equations of the first kind represent a natural generalization of the Riccati equation.

If and and for , then Abel's differential equation of the first kind can be reduced to the normal form by substitution of variables [2]. In the general case, Abel's differential equation of the first kind cannot be integrated in closed form, though this is possible in special cases [2]. If and , , Abel's differential equation of the second kind can be reduced to Abel's differential equation of the first kind by substituting .

Abel's differential equations of the first and second kinds, as well as their further generalizations

have been studied in detail in the complex domain (see, for example, [3]).
