In the mathematics mathematical study of the differential geometry of surfaces , the Bertrand Diquet Puiseux theorem expresses the Gaussian curvature of a surface in terms of the circumference of a geodesic circle, or the area of a geodesic disc. The theorem is named for Joseph Bertrand , Victor Puiseux , and C.F. Diquet. Let p be a point on a smooth surface M . The geodesic circle of radius r centered at p is the set of all points whose geodesic distance from p is equal to r . Let C r denote the circumference of this circle, and A r denote the area of the disc contained within the circle. The Bertrand Diquet Puiseux theorem asserts that math K p lim r to 0 3 frac 2 pi r C r pi r 3 lim r to 0 12 frac pi r 2 A r pi r 4 . math The theorem is closely related to the Gauss Bonnet theorem .

unreferenced date August 2009 Image Pierre Ossian Bonnet.jpg thumb Pierre Ossian Bonnet Pierre Ossian Bonnet 22 December 1819, Montpellier 22 June 1892, Paris was a France French mathematician . He made some important contributions to the differential geometry of surfaces, including the Gauss Bonnet theorem . Biography Early years Pierre Bonnet attended the Coll ge in Montpellier. In 1838 he entered the Ecole Polytechnique in Paris. He also studied at the cole Nationale des Ponts et Chauss es . Middle years In graduating he was offered a post as an engineer. After some thought Bonnet decided on a career in teaching and research in mathematics instead. Turning down the engineering post had not been an easy decision since Bonnet was not well off financially. He had to do private tutoring so that he could afford to accept a position at the Ecole Polytechnique in 1844. One year before this, in 1843, Bonnet had written a paper on the convergence of series with positive terms. Another paper on series in 1849 was to earn him an award from the Brussels Academy. However between these two papers on series, Bonnet had begun his work on differential geometry in 1844. Bonnet was elected to the Academy of Sciences in 1862 to replace Jean Baptiste Biot Biot . He defeated Bour for this position. From 1868 Bonnet assisted Michel Chasles Chasles at the Ecole Polytechnique, and three years later he became a director of studies there. In addition to this post he also taught at the Ecole Normale Sup rieure. In 1878 Bonnet succeeded Le Verrier to the chair at the Sorbonne, then in 1883 he succeeded Liouville as a member of the Bureau des Longitudes. Bonnet did important work on differential geometry. In addition Serret , Jean Fr d ric Frenet Frenet , Joseph Louis Fran ois Bertrand Bertrand and Pierre Puiseux Puiseux worked in France on this topic. Bonnet made major contributions introducing the notion of geodesic curvature. A formula for the line integral of the geodesic curvature along ... more details

Just to the east northeast of Doppelmayer lies the nearly submerged crater Puiseux crater Puiseux . The rim of Doppelmayer is nearly round, but is worn and eroded. The most intact section is the southwest half, while in the northeast the rim descends beneath the Lunar mare mare , leaving only a slight rise in the surface. The interior has been flooded by lava, leaving a large raised ridge in the center. A small range of hills curves to the west and north from the southern end of this ridge, forming a feature that is nearly concentric with the crater s outer rim. The crater is named after Johan Gabriel Doppelmayr by Johann Hieronymus Schr ter in 1791 Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater mid point that is closest to Doppelmayer. class wikitable width 25 style background eeeeee Doppelmayer width 25 style background eeeeee Latitude width 25 style background eeeeee Longitude width 25 style background eeeeee Diameter align center A align center 29.8 S align center 43.1 W align center 10 km align center B align center 30.5 S align center 45.4 W align center 11 km align center C align center 30.3 S align center 44.1 W align center 7 km align center D align center 31.8 S align center 45.8 W align center 9 km align center G align center 28.9 S align center 44.9 W align center 15 km align center H align center 28.8 S align center 43.2 W align center 10 km align center J align center 24.5 S align center 41.1 W align center 6 km align center K align center 24. ... more details

However, the institutions of Austria Hungary did not permit a Jew to advance to a senior position without renouncing his faith and embracing Catholicism . The director of the observatory Karl L. Littrow was a correspondent of Urbain Le Verrier , director of the Paris Observatory and he secured a position there for Loewy in 1860. After going to France, Loewy become a naturalised French citizen. He worked on the orbit s of asteroid s and comet s and on the measurement of longitude , improving the accuracy of the Connaissance des Temps . He also worked on optics and the elimination of the aberration of light . He was elected a member of the Bureau des Longitudes in 1872 and of the Acad mie des Sciences in 1873. Loewy became director of the Paris Observatory in 1896, reorganising the institution and establishing a department of physical astronomy. He further spent a decade working with Pierre Puiseux on an Atlas cartography atlas of the Moon composed of 10,000 photographs, L Atlas photographique de la Lune 1910 , the definitive basis for lunar geography for over half a century.
