Élisabeth Lutz

{{Short description|French mathematician (1914–2008)}}

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.{{cite book|last1=Silverman|first1=Joseph H.|author1-link=Joseph H.

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 $p$-adic fields.{{cite journal | first=Anthony W. |last=Knapp | authorlink=Anthony W.
