AN ENTROPY CONTINUATION METHOD FOR A CLASS OF THE PERIODICITY PROBLEMS OF ORDINARY DIFFERENTIAL EQUATIONS
In this paper, we propose an entropy continuation method for a class of the periodicity problems, which is an important and attracting topic in the qualitative theory of differential equations. Compared with the existing results in the literature, our results not only can handle the equivalent problems of the periodicity problems with many constraints, but also can handle the case of equality constraints.
