Timeline
Gheorghe Călugăreanu (16 June 1902 – 15 November 1976) was a Romanian mathematician, professor at Babeș-Bolyai University, and full member of the Romanian Academy.
He was born in Iași, the son of physician, naturalist, and physiologist Dimitrie Călugăreanu.
From 1913 to 1921 he studied at the Gheorghe Lazăr High School in Bucharest, after which he attended University of Cluj, graduating in 1924.
In 1926 he went to Paris to pursue his studies at the Sorbonne, supported by a scholarship from the Romanian government.
He obtained his Ph.D. in mathematics in 1929, with thesis Sur les fonctions polygènes d'une variable complexe written under the direction of Émile Picard and defended before a jury that also included Édouard Goursat and Gaston Julia.
After returning to Romania, he was appointed assistant the University of Cluj in 1930; he was promoted to lecturer in 1934 and named professor in 1942.
From 1953 to 1957 he served as Dean of the Faculty of Mathematics.
He was elected a corresponding member of the Romanian Academy in 1955, and he became a full member in 1963.
Călugăreanu studied the theory of functions of a complex variable (meromorphic functions, univalent functions, analytic extension invariants), as well as differential geometry and algebraic topology, especially in knot theory.
In a paper from 1959, he showed how to calculate the writhe of a knot by means of a Gaussian double integral.
Călugăreanu's formula has since been pursued by James H. White and F. Brock Fuller, leading to applications in DNA topology, where writhe is used to describe the amount a piece of DNA is deformed as a result of torsional stress (a phenomenon known as DNA supercoiling).
The topological interpretation of helicity in terms of the Gauss linking number and its limiting form has been called the "Călugăreanu invariant" by Keith Moffatt and Renzo L. Ricca.
In his best-known work, he established in 1961 the following foundational result regarding the writhe of a knot: take a ribbon in three-dimensional space, let be the linking number of its border components, and let be its total twist; then the difference depends only on the core curve of the ribbon.
He died of cancer in Cluj-Napoca in 1976; following his wishes, he was cremated and the urn was deposited at Bellu Cemetery in Bucharest.
