What has the author Mary Cartwright written?

You're likely thinking of Dame Mary Cartwright, a renowned British mathematician. She's known for her contributions to dynamical systems and nonlinear differential equations, particularly her work on the van der Pol equation, which models various physical phenomena.

Here are some of her key works:

* "Forced Oscillations in Nonlinear Systems" (1951): This book is considered a foundational work in the field of nonlinear dynamics. It examines the behavior of forced oscillations in systems described by nonlinear differential equations.

* "Nonlinear Differential Equations" (1957): This book, written with J.E. Littlewood, delves deeper into the theory of nonlinear differential equations, exploring topics like stability, periodic solutions, and bifurcations.

* "The Mathematical Papers of Sir Edmund Whittaker" (1962): This was an edited collection of the works of her mentor, Edmund Whittaker.

* "Selected Papers of Mary Cartwright" (1990): A compilation of her most important research papers, offering insights into her contributions to mathematics.

While not as widely recognized as her mathematical works, Dame Mary Cartwright also authored a book called "The Place of Mathematics in Civilization" (1956), which explores the role of mathematics in shaping our understanding of the world.

It's important to note that there might be other authors named Mary Cartwright, but Dame Mary Cartwright is the one known for her significant contributions to mathematics.
