The construction of regular guiding functions
We study the existence of periodic solutions for a class of systems of first-order nonlinearordinary differential equations on the plane. Using an a priori estimate of periodic solutions, weestablish the homotopy invariance of the solvability property of the periodic problem, give adescription of the homotopy classes, and prove a theorem about a necessary and sufficientcondition for the solvability of the periodic problem.
