Poncelet, Jean-Victor Poncelet was born in Metz. He took part in Napoleon's Poncelet had been a pupil of Gaspard Monge , the originator of modern synthetic geometry, but Poncelet also used analytical geometry and contributed greatly to the development of the relatively new synthetic (projective) geometry. He became the centre of controversy over the principle of continuity, and developed the circular points at infinity. Poncelet developed a new model of a variable counterweight drawbridge, which he described and publicized in 1822. His most important technical contributions were concerned with hydraulic engines, such as Poncelet's water wheel, with regulations and with dynamometers, as well as in devising various improvements to his own fortification techniques.

Poncelet studoval na École Polytechnique Poncelet - zakladatel projektivní geometrie Jean-Victor Poncelet byl jedním ze zakladatelù moderní projektivní geometrie. Za Napoleonova tažení do Ruska pracoval Jean-Victor Poncelet od roku 1812 jako inženýr. V Rusku byl ranìn a upadl do zajetí (1813), ze kterého se vrátil do Francie v roce 1914. V ruském vìzení studoval Poncelet projektivní geometrii - pojednání o analytické geometrii Applications d'analyse et de géométrie. Pojednání bylo publikováno až po 50 letech. V letech 1815 až 1825 pùsobil Poncelet v Metz jako armádní inženýr. V letech 1820 až 1821 Jean-Victor Poncelet spolu s Brianchonem prokázal Feuerbachùv teorém V roce 1822 publikoval Jean-Victor Poncelet Traité des propriétés projectives des figures , ve které studoval vlastnosti, které zùstávají pøi projekci invariantní. Tato jeho práce obsahuje základní myšlenky projektivní geometrie, jako je perspektiva, involuce a cirkulární body v nekoneènu. Mechanika V letech 1825 až 1835 byl Jean-Victor Poncelet profesorem mechaniky.

Jean-Victor Poncelet was a pupil of Monge. As a lieutenant of engineers in 1812, he took part in Napoleon's Russian campaign, in which he was abandoned as dead at Krasnoy and imprisoned at Saratov. He returned to France in 1814. During his imprisonment Poncelet studied projective geometry and wrote , 2 vol. (1862-64; "Applications of Analysis and Geometry"). This work was originally planned as an introduction to his celebrated (1822; "Treatise on the Projective Properties of Figures"), for which Poncelet is regarded as one of the greatest projective geometers. His development of the pole and polar lines associated with conics led to the principle of duality and a dispute over priority for its discovery. His principle of continuity, a concept designed to add generality to synthetic geometry, led to the introduction of imaginary points. From 1815 to 1825 Poncelet was occupied with military engineering at Metz, and from 1825 to 1835 he was professor of mechanics at the

PONCELET JEAN VICTOR (1788-1867) Militaire et mathématicien français - né le 1er Juillet 1788 à Metz, Lorraine, France - décédé le 22 Décembre 1867 à Paris, France Dans son grand traité de géométrie projective, Poncelet étudie les propriétés des figures qui sont invariantes par projection centrale ; cette méthode apparaît comme étant un outil très efficace : elle permet à Poncelet d’établir les principales propriétés des coniques et des quadriques et de traiter la théorie des polygones. Il énonce aussi le " principe de continuité ", qui affirme que les propriétés d’une figure, invariantes par certaines transformations, ne sont pas modifiées lorsque la figure prend une position limite. À l’aide de ce principe, Poncelet est amené à considérer les points et droites qui disparaissent à l’infini ou deviennent imaginaires ; il élabore la théorie des transformations par polaires réciproques et le "principe de dualité".

Laboratoire Poncelet The Laboratoire Jean-Victor Poncelet (former LIFR MI Founding Agreement between the CNRS (the French National Center for Scientific Research) and the IUM (the Independent University of Moscow). This agreement was signed on March 11, 2002, at the French Embassy in Moscow by the Director of the CNRS, Madame G.Berger and the President of the IUM, professor Yu.Ilyashenko in the presence of the Ambassador, Monsieur C.Blanchemaison and several eminent personalities of the French and Russian scientific world. Three institutes of the Russian Academy of Sciences (RAS), the Steklov Institute (MIAN), the Central Economics and Mathematics Institute (TsEMI) and the Institute for Information Transmission Problems (IPPI) are associated to this agreement. The aim of the Laboratory is to bring together into a joint team several French and Russian researchers working on a wide spectrum of mathematical problems, ready to interact with the other sciences. The lab is at present a small one (8-10 collaborators) and has a modest budget, but its founders expect that it will have an influence far surpassing the direct scientific contribution of its permanent staff: it is meant to function as a meeting place for visitors coming from France (not only from Paris) and from Russia (not only from Moscow) for conferences , seminars, and colloquia, or for short-term visits.

Il Prof. Marcel BERGER (IHES), visitatore presso l’Universita’ di Roma « La Sapienza » nel periodo 2-16 ottobre 2004, terra’ un ciclo di 4 conferenze ROMA 4 LECTURES ABSTRACTS First lecture : “Jean-Victor PONCELET (Metz 1788-Paris 1867) : the metamorphoses of his life and of his fascinating theorem” Abstract : Prisoner of the Russians during the Napoleon retreat, during these two years, having only at his disposal the memory of Monge lectures at Ecole polytechnique where his was a pupil, Poncelet managed to become the father of projective geometry (real as well as complex), including also for this geometry three new concepts : that of continuity, that of duality, that of projective transformation. With these notions he found many new theorems, in particular for conic sections. But the one of them, which concerns polygons which are at the same time inscribed in a conic and circumscribed to another, exercised a real fascination on all mathematicians who became aware of it, and still exercises that fascination. Besides its beauty, another reason is that there is no simple proof of it. Jacobi, to deeply inderstand it, discovered that it is the elliptic functions which are at the root of it. We will present in the lecture few different proofs of the theorem, quote the answers to difficult questions of finding explicit formulas, questions which stem out directly from the theorem. There is no year today where does not appear
