Axel Thue (Norwegian: [tʉː]; 19 February 1863 – 7 March 1922) was a Norwegian mathematician, known for his original work in diophantine approximation and combinatorics.

Work

[edit]

Thue published his first important paper in 1909.[1]

He stated in 1914 the so-called word problem for semigroups or Thue problem, closely related to the halting problem.[2]

His only known PhD student was Thoralf Skolem.

The esoteric programming language Thue is named after him.
