Lectures on Ordinary Differential Equations calculus of finite differencesHailed by The American Mathematical Monthly as "a rigorous and lively introduction," this text explores a topic of perennial interest in mathematics. The author, a distinguished mathematician and formulator of the Hurewicz theorem, presents a clear and lucid treatment that emphasizes geometric methods. Topics include first order scalar and vector equations, basic properties of linear vector equations, and two dimensional nonlinear autonomous systems.
