Proof of the Heawood conjecture for nonorientable surfaces by
John William Theodore Youngs(
Book
)
2 editions published in 1970 in English and held by 38 WorldCat member libraries worldwide
The paper provides a proof of the fact that the chromatic number of the nonorientable surface which is a sphere with q crosscaps is the integral part of (7 + the(square root of (1+24q))/2), unless q = 2. In the exceptional case the chromatic number is 6. (Author)

The Heawood mapcoloring problem: cases 1, 7, and 10 by
John William Theodore Youngs(
Book
)
2 editions published in 1969 in English and held by 18 WorldCat member libraries worldwide
The paper gives a proof of Heawood's conjecture that the chromatic number of an orientable surface of genus p is equal to the integral part of (7 + the square root of 1 + 48p)/2 whenever the expression is congruent to 1, 7, or 10 modulo 12. Proof of Heawood's theorem involves twelve special cases. This memorandum presents the proof for cases 1, 7, and 10
