The k direction in a k.p model ?

[QUOTE="DrDu, post: 6021330, member: 210532"] ##\Gamma##, M , ##\Sigma##, means that the hamiltonian is invariant under a specific group of rotations and reflections, respectively, which also leave k invariant. These groups are called the "little groups of the wavevector". This are sub groups of the point group under which ##\Gamma## is invariant. Look up which elements they contain in case of the Point Group of GaN and make sure that for the coice of k, your Hamiltonian is invariant under the corresponding transformations. [/QUOTE]
