Victor Neumann Lara, Mexican mathematician (Huejutla de Reyes, Hidalgo State 06 June 1933 – Puebla 26 February 2004) From German father Introduced the notion of dichromatic number of a digraph and the definition of the chromatic number of a digraph (1982) With L. Montejano proved a Mengerian theorem for long paths (1984) With J.

Puga Espinosa gave necessary and sufficient conditions for a dendroid to be a dendrite (1993) With S.
