Élisabeth Lutz (May 14, 1914 – July 31, 2008) was a French mathematician.
The Nagell–Lutz theorem in Diophantine geometry describes the torsion points of elliptic curves; it is named after Lutz and Trygve Nagell, who both published it in the 1930s.
[1][L37] Lutz was a student of André Weil at the University of Strasbourg, from 1934 to 1938.
She earned a thesis for her research for him, on elliptic curves over
-adic Diophantine approximation at the University of Grenoble in 1951 under the supervision of Claude Chabauty; her dissertation was Sur les approximations diophantiennes linéaires
