Description: St.-Pétersbourg, l'Académie Impériale des Sciences, 1906. Large 4to (33.5 x 25.1 cm). 225 pp. Original printed wrappers. = Important contribution to the properties of spherical liquid masses by the Russian mathematician Alexandr Mikhailovich Lyapunov (1857-1918). "He created the modern theory of the stability of a dynamic system" (Wikipedia). "At the beginning of 1901 he was elected an associate member of the St. Petersburg Academy of Sciences, and at the end of that year he became an academian in applied mathematics. In St. Petersburg, Lyapunov devoted himself completely to scientific work. He returned to the problem that Chebyshev had placed before him [in 1882] and, in an extensive series of papers which continued until his death, developed the theory of figures of equilibrium of rotating heavy liquids and of the stability of these figures" (DSB). Published by the academy, but this copy separately, not in their series of 'Mémoires'. Uncut. Spine reinforced with transparent tape; small label on front wrapper, old, cancelled stamp on the title page;some occasional light spotting, otherwise a very good copy. Rare. DSB VIII, 560.
