Victor Vâlcovici (n. 21 septembrie 1885, Galaţi - d. 21 iunie 1970, Bucureşti) a fost matematician, profesor şi membru al Academiei Române.

Biografie

Victor Vâlcovici a făcut liceul la Brăila, apoi a urmat Facultatea de Ştiinţe la Universitatea din Bucureşti (1904 - 1907). Studiile superioare le-a definitivat la Universitatea din Gottingen, obţinând aici doctoratul în matematică, în 1913.

După ce s-a reîntors în ţară, a fost numit profesor la catedra de Matematică de la Universitatea din Iaşi. În 1921 a fost detaşat la nou-înfiinţata Şcoală Politehnică de la Timişoara, fiind şi primul profesor de mecanică raţională. La Timişoara a pus bazele Societăţii Ştiinţifice din Politehnică şi a publicaţiei "Bulletin scientifique de l'Ecole Politehnique". A condus şi „Revista matematică” din Timişoara, înfiinţată de Traian Lalescu.

În anul 1930 se mută la Universitatea din Bucureşti. Între 1931 - 1932 este numit ministru al Lucrărilor Publice, în cabinetul condus de Nicolae Iorga. De asemenea, în cariera sa politică a ajuns deputat. În 1936 este numit membru corespondent al Academiei Române (membru titular din 1965).

Cercetări

Victor Vâlcovici a intreprins o bogată activitate de cercetare. Printre cele mai importante teme studiate se numără:

  • echilibrul unui solid rigid aşezat pe o suprafaţă elastică (1931);
  • mişcarea solidului rigid (1933);
  • caracterul involuntiv al ecuaţiilor mişcărilor relative (1937);
  • mişcarea corpului solid rigid într-un fluid vâscos (1937);
  • teorema generală a mişcării sistemelor (1938);
  • mişcarea cu traiectorii plane (1941);
  • distribuţia axelor principale de inerţie (1944);
  • principiul lui D'Alambert-Lagrange (1945);
  • teoria rachetei (1949);
  • teoria suprafeţelor lui Bernoulli în mişcarea fluidelor barotrope - a stabilit ecuaţiile de mişcare a fluidelor pe aceste suprafeţe şi care îi poartă numele (Suprafeţele "Bernoulli - Vâlcovici");
  • principiul deplasărilor virtuale (1961);
  • axiomele staticii solidului rigid (1962)
  • etc.
