Abstract
Hadwiger's Conjecture seems difficult to attack, even in the very special case of graphs G of independence number α (G) = 2. We present some results in this special case.Keywords: Hadwiger's Conjecture, complete minor, independence number, connected matching.
2000 Mathematics Subject Classification: 05C15, 05C83.
