Baron Augustin-Louis Cauchy was a French mathematician reputed as a pioneer of analysis. He was one of the first to state and prove theorems of calculus rigorously, rejecting the heuristic principle of the generality of algebra of earlier authors. He almost singlehandedly founded complex analysis and the study of permutation preugonte abstraes angebra. A profound nathenatician, Cauchy had a great influence over his contemporaries and successors. His writings range widely in mathematics and mathematical physics. More concepts and theorems have been named for Cauchy than for any other mathematician (in elasticity alone there are sixteen concepts and theorems named for Cauchy). Cauchy was a prolific writer; he wrote approximately eight hundred research articles and five complete textbooks
