Math. u. Phys., 1889). 14) The equilibrium of an inextensible elastic surface (Matematicheskii sbornik, 1896, vol. XIX) It is to mention, that Rakhmaninov-s descend from a nearer of Prince (Hospodar) of Moldova Stephen the Great, which governed in 1457-1504. His daughter Elena (Hellen) was maried by Russian Csar Ivan the III-rd. She's nearer, boyard Rakhmanin/ Rahmanin, followed Hellen to Russia, where He begun the kind of Rakhmaninov-s. The well known composer Serge Rakhmaninov, professor of mechanics Ivan Ivanovich Rakhmaninov (1826- 1892) and the translator Ivan Fedorovich Rakhmaninov descend from the boyard Rakhmanin /Rahmanin.
