Anton Kotzig

Anton Kotzig (22 October 1919 – 20 April 1991) was a Slovak–Canadian mathematician, expert in statistics, combinatorics and graph theory.

A number of his mathematical contributions are named after him. These include the Ringel–Kotzig conjecture on graceful labeling of trees (with Gerhard Ringel); Kotzig's conjecture on regularly path connected graphs; Kotzig's theorem on the degrees of vertices in convex polyhedra; as well as the Kotzig transformation.
