Victor Neumann-Lara
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. Urrutia showed that in any set of n points in the plane in general position there is always a pair of points such that any circle through them contains at least n=2 points (1985) With E. Rivera Campo proved a Chvátal-Erdos type theorem concerning the existence of a spanning m-tree (1991) With I. Puga Espinosa gave necessary and sufficient conditions for a dendroid to be a dendrite (1993) With S. Hazan proved that every finite partially ordered set whose comparability graph is clique null has the fixed point property (1996) Conjectured the existence of infinite families of vertex critical-r-dichromatic circulant tournaments (1997) Introduced acyclic disconnection of a digraph (1999) With F.
