Extension de la méthode de laplace aux équations [see image] + [see image]
Häftad bok.
Mycket gott skick. Från Wiki: "[...] (Petrén) blev filosofie doktor 1912 vid Lunds universitet på avhandlingen Extension de la méthode de Laplace. Hon var den första kvinnan i Sverige som disputerade i matematik." --- Gleerups, Lund 1911. 165 pages in softcover with structure surface wrappers which are somewhat stiffer than the rest of the pages. Text in french, and illustrated with various (from my point of view complicated) equations. Measure (base x height): 21 x 29 cm. ---
