His work also includes important results in conformal representations and in the theory of boundary correspondence.

He received there his doctorate in 1938 under Michael Fekete with thesis Conformal representation and univalent functions.

Conformal Representation, Cambridge 1932 (Cambridge Tracts in Mathematics and Physics)

Jacqueline Lelong-Ferrand (17 February 1918, Alès, France - 26 April 2014, Sceaux, France) was a French mathematician who worked on conformal representation theory, potential theory, and Riemannian manifolds.

Abstract: A method for the generation of quasi-isometric boundary-fitted curvilinear coordinates for arbitrary domains is developed on the basis of the quasi-isometric mappings theory and conformal representation of spherical and hyperbolic geometries.
