This is the text and invited lecture given at the 20th Annual Meeting of the Australian Mathematical Society in Perth, May 1976.
In this talk I want to give a survey of some of the areas of research in ordinary differential equations. In view of the vastness of the field, the limited thime available and may own inadequacies I will restrict attention to problems in which I have been involved in some way, although I won't be speaking about my own work. Even with this restriction it will be necessary to be somewhat superficial. However, in spite of all these drawbacks, I thought it would assist communication among mathematicians simply to have an idea of what other people are doing. Since this is my purpose I will not mention the quite mild smoothness hypotheses in the statements of some results.
