overviewBaron Augustin-Louis Cauchy FRS FRSE (/koʊˈʃiː/; French: [oɡystɛ̃ lwi koʃi]; 21 August 1789 - 23 May 1857) was a French mathematician, engineer, and French mathematician who made a pioneering contribution to a number of mathematical disciplines. He was a physicist: mathematical analysis and continuum mechanics. He was one of the first to rigorously disprove and prove the theory of mathematics, rejecting the intuitive principle of the generality of algebra of earlier authors. He established the study of permutation groups in complex analysis and abstract algebra almost from a single source.
A profound mathematician, Cauchy had a great influence on his contemporaries and successors; Hans Freudenthal, “More concepts and theorems have been named for Cauchy relative to any other mathematician (there are sixteen concepts and theorems named for Cauchy in flexibility alone).” Cauchy was a prolific writer; He has authored nearly eight hundred research papers and five complete textbooks on various topics in mathematics and mathematical physics. French mathematician. He left the École Polytechnic and became a technical officer, but in 1815 he returned to the École Polytechnique as Professor of mathematics. Support for the royal party, which had returned to exile in the July Revolution of 1830, turned to professor at the University of Paris in 1838 in 1840. Continuity of functions, limit, convergence of series, established modern analytics, formed the theory of complex number functions and proved the solution theorem of differential equation. Also elasticity, fluids, optics etc.
