    • Hadwiger's Conjecture On Circular Arc Graphs 

      Belkale, Naveen (2009-04-30)
      Conjectured in 1943, Hadwiger’s conjecture is one of the most challenging open problems in graph theory. Hadwiger’s conjecture states that if the chromatic number of a graph G is k, then G has a clique minor of size at ...
