| '''Eugène Charles Catalan''' (30 May 1814 – 14 February 1894) was a [[France|French]] and [[Belgium|Belgian]] [[mathematician]].
| |
| | |
| == Biography ==
| |
| | |
| Catalan was born in [[Bruges]] (now [[Belgium]], then part of the [[First French Empire]]), the only child of a French jeweller by the name of Joseph Catalan, in 1814. In 1825, he traveled to Paris and learned mathematics at [[École Polytechnique]], where he met [[Joseph Liouville]] (1833). In 1834 [http://www-history.mcs.st-and.ac.uk/Biographies/Catalan.html he was expelled from university] and went to [[Châlons-en-Champagne|Châlons-sur-Marne]], where he received a post after graduating. Catalan came back to the École Polytechnique, and, with the help of Liouville, obtained his degree in mathematics in 1841. He went on to Charlemagne College to teach descriptive geometry. Though he was politically active and strongly left-wing, leading him to participate in the [[1848 Revolution]], he had an animated career and also sat in the France's Chamber of Deputies. Later, in 1849, Catalan was visited at his home by the French Police, searching for illicit teaching material; however, none was found.

| | |
| The [[University of Liège]] appointed him chair of analysis in 1865. In 1879, still in Belgium, he became journal editor where he published as a foot note [[Paul-Jean Busschop]]'s theory after refusing it in 1873 - letting Busschop know that it was too empirical. In 1883, he worked for the [[The Royal Academies for Science and the Arts of Belgium|Belgian Academy of Science]] in the field of number theory. He died in [[Liège (city)|Liège]], [[Belgium]] where he had received a chair.
| |
| | |
| == Work ==
| |
| He worked on [[continued fraction]]s, [[descriptive geometry]], [[number theory]] and [[combinatorics]]. He gave his name to a unique surface (periodic minimal surface in the space <math>\mathbb{R}^3</math>) that he discovered in 1855. Before that, he had stated the famous [[Catalan's conjecture]], which was published in 1844 and was eventually proved in 2002, by the [[Romania]]n mathematician [[Preda Mihăilescu]]. He introduced the [[Catalan number]]s to solve a [[combinatorics|combinatorial]] [[Catalan's problem|problem]].
