Linkage disequilibrium mapping exploits the fact that at genetic markers close enough to a disease locus on a particular chromosome, we expect to find an association between the disease and marker alleles. Furthermore, the magnitude of the association is expected to follow a unimodal curve when plot

One of the most widely used applications of block theory to the U w x structure theory of finite groups is Glauberman's Z -theorem 2 , which asserts that if t is an involution of a finite group G which is not conjugate in G to any other involution of a Sylow 2-subgroup containing t, then Ε½ . Ε½ .

## Abstract This paper is written in the spirit of the author's book: __Map Color Theorem__ (1974). We try to develop the Map Color Theorem in a combinatorial way, circumventing the unwieldy embedding theory. Similar (but not identical) generalizations have recently and independently been developed

It is proved that the choice number of every graph G embedded on a surface of Euler genus Ξ΅ β‰₯ 1 and Ξ΅ = 3 is at most the Heawood number H(Ξ΅) = (7 + √ 24Ξ΅ + 1)/2 and that the equality holds if and only if G contains the complete graph K H(Ξ΅) as a subgraph.
