Oeuvres complètes: Series 2 (Cambridge Library Collection - Mathematics) (French Edition) by Augustin-Louis Cauchy

Augustin-Louis, Baron Cauchy (1789-1857) was the pre-eminent French mathematician of the nineteenth century. He began his career as a military engineer during the Napoleonic Wars, but even then was publishing significant mathematical papers, and was persuaded by Lagrange and Laplace to devote himself entirely to mathematics.
