Sigve Tjøtta (born 1 March 1930) is a Norwegian mathematician.

Early life[]

He was born in Klepp. He took the cand.real. degree in 1954 and the dr.philos. degree in 1960, both at the University of Oslo.[1] His doctoral thesis was On 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 a research assistant in Oslo from 1954 to 1956, 1957 to 1958 and 1959 to 1960.[1] In between he studied at Brown University from 1956 to 1957 and at the Max Planck Institute. Among his advisors were Johan Peter Holtsmark.[3]

Career[]

He was appointed docent at the University of Bergen in 1960, and was promoted to professor in 1963. He succeeded , and had responsibility for the university's education in applied mathematics. His fields of research include plasma, nonlinear acoustics, hydroacoustics and acoustic streaming.[3] He was also the dean of the Faculty of Mathematics and Natural Sciences from 1975 to 1977,[4] and has held positions in NAVF, , and in the national committee of the International Union of Theoretical and Applied Mechanics. He has also been a visiting scholar at the University of Texas.[1]

Personal life[]

Tjøtta married Jacqueline Naze, a colleague, in 1964—they barely survived a car crash sustained on their honeymoon. They have since done extensive research together.[3] After retirement from the professor chair, the couple moved to Oslo.[4]

Tjøtta's most prominent hobby is long-distance running. He discovered his talent during a stay in the United States, where jogging was popular.[5] He ran the marathon in 3:17.02 hours at the age of 66,[6] and the half marathon in 1:43.09 hours at the age of 75.[7]

Honors[]

Together with his wife, Tjøtta won a prize in underwater acoustics from the French Academy of Sciences. He is a fellow of the Acoustical Society of America,[3] and a member of the Norwegian Academy of Science and Letters.[8] In 2002 he was decorated as a Knight, First Class of the Royal Norwegian Order of St. Olav.[4]
