    Ibrāhīm ibn Sinān: On Analysis and Synthesis.Hélène Bellosta - 1991 - Arabic Sciences and Philosophy 1 (2):211.
    This paper is devoted to Ibn Sinn's text deals with two distinct, though closely related, subjects. First he considers the classification of problems, founded on the logical criteria which are the number and degree of indetermination of the solutions and the number of hypotheses and their possible independence. This classification does not replace the Hellenistic one, which remains relevant insofar as it purports to solve geometrical problems, but complements it and has a different frame of reference, applying principally to algebra, (...)

    Le traité de thābit Ibn qurra sur _la figure secteur_.Hélène Bellosta - 2004 - Arabic Sciences and Philosophy 14 (1):145-168.
    Suscités par la reprise massive de la recherche en astronomie au IXe siècle dans le monde islamique et essentiellement à Bagdad, laquelle nécessite des outils mathématiques nouveaux, une floraison de traités, tant astronomiques que mathématiques, voit le jour à cette époque. D'entre les traités mathématiques, un certain nombre est consacré à la ‘‘figure secteur”, c’est-à-dire au théorème dit ‘‘de Ménélaüs” sur la sphère, lequel généralise le théorème dit ‘‘de Ménélaüs” dans le plan. Ce théorème de Ménélaüs sur la sphère, ou (...)

    De l'usage Des coniques chez ibrāhīm Ibn sinān.Hélène Bellosta - 2012 - Arabic Sciences and Philosophy 22 (1):119-136.
    Once Apollonius' Conics had been translated from Greek into Arabic, they became a main reference and the principal tool in studying solid problems, algebraic equations of 3rd and 4th degrees, infinitesimal mathematics, etc. Mathematicians of the 9th–10th centuries also studied the conic sections' constructions, as well as their continuous drawing and their drawing by points. Ibrāhīm ibn Sinān, as his grandfather Thābit ibn Qurra, was one of the most active and inventive mathematicians in these fields. Late Hélène Bellosta examined in (...)

    De l'Usage Des Coniques Chez Ibrāhīm Ibn Sinān.Hélène Bellosta - 2012 - Arabic Sciences and Philosophy 22 (1):119-136.
    RésuméUne fois lesConiquesd'Apollonius traduits en arabe, ces livres sont devenus la référence indispensable et le principal instrument dans l'étude des problèmes solides, des équations algébriques des 3eet 4edegrés, des problèmes des mathématiques infinitésimales, etc. Les mathématiciens desixe-xesiècles ont également étudié les constructions des sections coniques ainsi que leur tracé par points et leur tracé continu. Ibrāhīm ibn Sinān (909–946), comme son grand-père Thābit ibn Qurra (826–901), était l'un des mathématiciens les plus actifs et les plus inventifs en ce domaine. Dans (...)
