Abstract: This paper concerns the existence of antiperiodic solutions of first order ordinary differential equations. Under the commonly used condition in the literature, via the homotopy method, a global method for finding those solutions is proved. Numerical examples show this mthod is effective.

Key words: antiperiodic solution, homotopy method, numerical example
