Primary sources

Vospominanija detstva, Barndomsminnen, 1889: an autobiography in Russian, first published in Swedish as Systrarna Rajevski in 1889. English translation: A Russian Childhood, Springer 1978.

Ur ryska lifvet: Systrarna Rajevski, 1889, is a semi-biographical literary adaptation in Swedish. Nihilistka, 1890, is a semi-biographical and unfinished novel in Russian. The play Kampen för lyckan is available in Swedish through Project Runeberg.

The mathematical articles from 1874–1888 deal with partial differential equations, Saturn’s rings, elliptic integrals and the rotation of a rigid body. The correspondence with Karl Weierstrass from 1870–1891 is crucial to understanding her mathematical development and working process.

• "The poet needs to perceive what others do not perceive, to see more deeply than others see. And the mathematician must do the same."
• "Mathematics opens up a new, wonderful world."
