Robert Frucht

Roberto fruit, full name Roberto fruit Wertheimer ( born August 9, 1906 in Brno Moravia, as Robert fruit, † 26 June 1997 ) was a German - Chilean mathematician.

His father was the editor Robert fruit. His family moved in 1908 to Berlin, where he later mathematics, physics and philosophy studied and in 1931 received his doctorate with a dissertation "On the representation of finite Abelian groups by collineations " when Isay Schur. A habilitation was denied him because of his Jewish origin and he turned to the work as an actuary for an insurance company in Trieste and decided after his release in early 1939 because of the threat of war with his now established family emigrate to Argentina, where he was first a job as a actuaries in Buenos Aires took.

Through the mediation of Robert Breusch, a contact from his Berlin period, he began teaching at the Universidad Santa María in Valparaíso ( Chile), from 1948 to 1968 he was dean of mathematical science faculty and emeritus since 1970.

His main area of ​​work was the graph theory, in which he now called the 1938 set of fruit proved by the finite to a given group is a finite graph with a isomorphic to the automorphism group can be found.

Since 1979, Roberto fruit was a corresponding member of the Chilean Academy of Sciences. He was also a member of the Argentine Mathematical Society and the American Mathematical Society. 1982 Roberto fruit was dedicated to a band of the Journal of Graph Theory.
