Jack Lemmon and Shirley MacLaine star in this acclaimed satire from writer-director Billy Wilder. Insurance clerk C.C. Baxter (Lemmon) lets his superiors use his apartment as a secret love nest and as a result begins to make his way up in the company. Things go awry when director Mr. Sheldrake (Fred MacMurray) wants to use the apartment for a rendevouz with Fran Kubelik (MacLaine), an elevator operator whom the young clerk already holds a candle for. The film won five Oscars including Best Picture, Best Director and Best Screenplay.

This book is intended to be an introduction to Delay Differential Equations for upper level undergraduates or beginning graduate mathematics students who have a reasonable background in ordinary differential equations and who would like to get to the applications quickly. The author has used preliminary notes in teaching such a course at Arizona State University over the past two years. This book focuses on the key tools necessary to understand the applications literature involving delay equations and to construct and analyze mathematical models involving delay differential equations. The book begins with a survey of mathematical models involving delay equations.
