Line 6:
The Hadwiger conjecture is named after [[Hugo Hadwiger]], who included it on a list of unsolved problems in 1957; it was, however, previously studied by {{harvtxt|Levi|1955}} and independently, {{harvtxt|Gohberg|Markus|1960}}. Additionally, there is a different [[Hadwiger conjecture (graph theory)|Hadwiger conjecture]] concerning [[graph coloring]]—and in some sources the geometric Hadwiger conjecture is also called the '''Levi–Hadwiger conjecture''' or the''' Hadwiger–Levi covering problem'''.
The [[conjecture]] remains unsolved even in three dimensions, though the two dimensional case was resolved by {{harvtxt|Levi|1955}}.
