Abstract : Major contributions were made in the following areas: (1) stability of dynamical systems; (2) nonlinear oscillations and (3) functionaldifferential equations. In the introduction, a brief description is given of the types of problems in this area that have been of interest. Section II is a summary of the work completed and contains a brief statement of some of the principal results. References to complete reports on the research are given. In almost all instances, complete reports on the research reported on below have been completed or are in preparation. With few exceptions, the results have been published in papers, in scientific journals or have been accepted for publication or manuscripts are being prepared for submission for publication. (Author)
