Georgi Delchev Bradistilov (Bulgarian: Георги Делчев Брадистилов; 25 October 1904 [12 October 1904O.S.] – 18 June 1977) was aBulgarian mathematician.[3]
Georgi Bradistilov, the fourth and youngest child in the family of the high-ranked civil servant at Bulgarian Ministry of Finance, Delcho Petkov Bradistilov (1866 – 1927), and teacher Nona Georgieva Bradistilova (née Motekova) (1876 – 1958), was born on 12 October 1904OS inPanagyurishte. He attended 3rd Sofiagymnasium and in 1922 enteredSofia University to study physics and mathematics. In 1927 he graduated with honors and the same year was appointed as assistant professor in mathematics. In the 1930s he studied at theUniversity of Paris and theUniversity of Munich. Bradistilov was one of the last students to takeArnold Sommerfeld's course intheoretical physics before his retirement.In 1938, he defended hisdoctorate, withOskar Perron as advisor, at the University of Munich.[4]
Upon his return to Bulgaria Dr Bradistilov taught asprivate docent at his alma materSofia University. In 1943 he joined as extraordinary professor and later as full professor the newly establishedHigher Technical School in Sofia, which after the Second World War was renamed the State Polytechnic. Apart from his teaching duties, he wrote the basic mathematicstextbooks used for many years by future Bulgarian engineers.
He wasrector of the State Polytechnic in Sofia from 1947 to 1948 and rector of theTechnical University of Sofia from 1962 to 1966. In 1958 he was awarded Doctor of Mathematics and Physics Science Degree. In 1966 he was elected corresponding member of theBulgarian Academy of Sciences.
Georgi Bradistilov's contributions to applied mathematics are related tononlinear differential equations and their applications tomechanics andelectrotechnics, toelectrostatic potential, tononlinear oscillations.[5]
He was notorious for his sense of humour and openness, for his love of arts and nature as well as for his refined taste, his wife being an artist educated inFlorence.
During his lifetime Georgi Bradistilov received many Bulgarian statedecorations and awards. Recently a street in Sofia near theTechnical University was named after him.
