The only monograph on the topic, this book concerns geometric methods in the theory of differential equations with quadratic right-hand sides, closely related t

Optimal control theory is a technique being used increasingly by academic economists to study problems involving optimal decisions in a multi-period framework.

Treats optimal problems for systems described by ODEs and PDEs, using an approach that unifies finite and infinite dimensional nonlinear programming.

Upper-level undergraduate text introduces aspects of optimal control theory: dynamic programming, Pontryagin's minimum principle, and numerical techniques for t

In the late 1950's, the group of Soviet mathematicians consisting of L. S. Pontryagin, V. G. Boltyanskii, R. V. Gamkrelidze, and E. F. Mishchenko made fundament
