picture info	Chazy Formation The Chazy Reef Formation is a mid-Ordovician limestone deposit in northeastern North America. It consists of some of the oldest reef systems built by a community of organisms rather than the deposit of a limited range of similar organisms, such as Stromatolite mounds deposited by ancient cyanobacteria. The reef structure was formed largely by cryptostome and trepostome bryozoa, some of the oldest known bryozoans, but corals made an early appearance, and stromatoporoids. The formation is named for the small town of Chazy, New York, where the reef was noted by James Hall in ''Palaeontology of New York'' (vol. I, 1847) and the fossils first studied by the Canadian paleontologist Elkanah Billings (1858, 1859). The reef extends from Tennessee to Quebec and Newfoundland, but its most easily studied outcropping is at Goodsell Ridge, Isle La Motte, the northernmost island in Lake Champlain; there, gentle uplift has tilted the sediments: the bedding planes now dip slightly to the north, ...

	Jean Chazy Jean François Chazy (15 August 1882, Villefranche-sur-Saône – 9 March 1955, Paris) was a French mathematician and astronomer. Life Chazy was the son of a small provincial manufacturer and studied mathematics at the École Normale Supérieure with completion of the agrégation in 1905. He received his doctorate in 1910 with thesis ''Équations différentielles du troisième ordre et d’ordre supérieur dont l’intégrale générale a ses points critiques fixes''. In 1911 he was ''maître de conférences'' for mechanics in Grenoble and then in Lille. In World War I he served in the artillery and became famous for accurately predicting the location of the German siege gun which bombarded Paris. After the war he was again professor in the ''Faculté des Sciences de Lille'' (which later became the Lille University of Science and Technology). Simultaneously he taught at the ''Institut industriel du Nord'' (École Centrale de Lille). In 1923 he was ''maître de conférences'' a ...

	Chazy Equation In mathematics, the Chazy equation is the differential equation : \frac = 2y\frac - 3 \left(\frac\right)^2. It was introduced by as an example of a third-order differential equation with a movable singularity that is a natural boundary for its solutions. One solution is given by the Eisenstein series Eisenstein series, named after German mathematician Gotthold Eisenstein, are particular modular forms with infinite series expansions that may be written down directly. Originally defined for the modular group, Eisenstein series can be generaliz ... :E_2(\tau) =1-24\sum \sigma_1(n)q^n= 1-24q-72q^2-\cdots. Acting on this solution by the group SL2 gives a 3-parameter family of solutions. References * * * Ordinary differential equations {{mathanalysis-stub ...
