Life
Albert Bäcklund studied from 1861 at the University of Lund a . a. Astronomy and math. From 1864 he worked at the astronomical observatory in Lund with Axel Möller, and in 1868 he received his doctorate there with a thesis on astronomical latitude determination. In 1869 he was a lecturer in astronomy and geometry in Lund. In 1874 he studied with Felix Klein in Leipzig and with Ferdinand von Lindemann in Erlangen with a travel grant . From 1876 he was an associate professor for mechanics and theoretical physics in Lund . In 1897 he was given a full professorship. From 1907 to 1909 he was rector at Lund University, and in 1910 he retired. After his retirement, he continued to work on differential geometry , especially in the general theory of relativity discovered in 1916 .
Bäcklund worked on Sophus Lie's contact transformations . Today he is best known for the Bäcklund transformation, named after him, between the solutions of partial differential equations (Mathematische Annalen, Vol. 13 to Bd. 19, 1875 to 1882). B. have applications in soliton theory . The simplest case are the real and imaginary parts of holomorphic functions that satisfy the Cauchy-Riemann differential equations and the Laplace equation .
In 1872 he became a member of the Royal Physiographical Society in Lund , in 1888 the Royal Swedish Academy of Sciences and in 1897 the Royal Society of Sciences in Uppsala .
