The concept of subcontraction-equivalence is defined, and 14 graphtheoretic properties are exhibited that are all subcontraction-equivalent if Hadwiger's conjecture is true. Some subsets of these properties are proved to be subcontraction-equivalent anyway. Hadwiger's conjecture is expressed as the

## dedicated to professor w. t. tutte on the occasion of his eightieth birthday Tutte made the conjecture in 1966 that every 2-connected cubic graph not containing the Petersen graph as a minor is 3-edge-colourable. The conjecture is still open, but we show that it is true, in general, provided it
## Abstract A graph __G__ is a quasiโline graph if for every vertex __v__ โ __V__(__G__), the set of neighbors of __v__ in __G__ can be expressed as the union of two cliques. The class of quasiโline graphs is a proper superset of the class of line graphs. Hadwiger's conjecture states that if a grap
## Abstract Hadwiger's conjecture states that every graph with chromatic number ฯ has a clique minor of size ฯ. In this paper we prove a weakened version of this conjecture for the class of clawโfree graphs (graphs that do not have a vertex with three pairwise nonadjacent neighbors). Our main resul
## Abstract A Short proof is given of the theorem that every grph that does not have __K__~4~ as a subcontraction is properly vertex 3โcolorable.
For any prime p congruent to 1 modulo 4, let (t+u -p)ร2 be the fundamental unit of Q(p). Then Ankeny, Artin, and Chowla conjectured that u is not divisible by p. In this paper, we investigate a certain relation between the conjecture and the continued fraction expansion of (1+p)ร2. Consequently, we
