Sigve Tjøtta (1 March 1930 – 28 August 2023) was a Norwegianmathematician.
He was born inKlepp. He took thecand.real. degree in 1954 and thedr.philos. degree in 1960, both at theUniversity of Oslo.[1] His doctoral thesis wasOn Some Non-linear Effects in Sound Fields, with Special Emphasis on the Generation of Vorticity and the Formation of Streaming Patterns.[2] He worked as aresearch assistant in Oslo from 1954 to 1956, 1957 to 1958 and 1959 to 1960.[1] In between he studied atBrown University from 1956 to 1957 and at theMax Planck Institute. Among his advisors wereJohan Peter Holtsmark.[3]
He was appointeddocent at theUniversity of Bergen in 1960, and was promoted to professor in 1963. He succeededOddvar Bjørgum, and had responsibility for the university's education inapplied mathematics. His fields of research includeplasma,nonlinear acoustics,hydroacoustics andacoustic streaming.[3] He was also the dean of theFaculty of Mathematics and Natural Sciences from 1975 to 1977,[4] and has held positions inNAVF,NTVF, and in the national committee of theInternational Union of Theoretical and Applied Mechanics. He has also been a visiting scholar at theUniversity of Texas.[1]
Tjøtta marriedJacqueline Naze, a colleague, in 1964—they barely survived a car crash sustained on theirhoneymoon. They have since done extensive research together.[3] After retirement from the professor chair, the couple moved toOslo.[4]
Tjøtta's most prominent hobby islong-distance running. He discovered his talent during a stay in the United States, wherejogging was popular.[5] He ran themarathon in 3:17.02 hours at the age of 66,[6] and thehalf marathon in 1:43.09 hours at the age of 75.[7]
He died in August 2023, aged 93.[8]
Together with his wife, Tjøtta won a prize inunderwater acoustics from theFrench Academy of Sciences. He is a fellow of theAcoustical Society of America,[3] and a member of theNorwegian Academy of Science and Letters.[9] In 2002 he was decorated as a Knight, First Class of theRoyal Norwegian Order of St. Olav.[4]
