✦ Synopsis

There are 24 rotations which rotate a cubic crystal into a standard orientation. Of these there is one (or more} for which the angle of rotation is least in ~itude and a calculation is made of the theoretical distribution of the corresponding axes of rotation in a random polycrystalline aggregate. This distribution can be used as a standard for assessing the degree of randomness in a cubic texture.

DISTRIBUTION DES AXES DE ROTATION DANS UN AGREGAT QUELCONQUE DE CRISTAUX CUBIQUES 11 existe 24 rotations qui peuvent tourner un cristal oubique en une orientation standard. De ces rotations une (ou plusieurs) correspond a l'angle de rotation le plus faibk; it est possible de calculer la distribution theorique des axes de rotation correspondants dans un agregat ~lyer~~ quelconque. Cette distribution peut 6tre utili&e oomme reference pour mesurer le de@ de hasard dane une texture cubique.

FW eine (oder mehrem) dieser Drehungen ist der Drehwinkel am kleinsten. Fur diesen Fall wird die theoretische Verteihmg der zugeharigen Drehaohsen in einer s~t~t~hen flagon Zusammenlagerung berechnet. Diese Verteilung ti als ein Normalfall fiir die Absohiitztmg des Verteihmgsgrades der Orientierungen in kubischen Strukturen bend& werden.

The eigenvalue distribution of a uniformly chosen random finite unipotent matrix in its permutation action on lines is studied. We obtain bounds for the mean number of eigenvalues lying in a fixed arc of the unit circle and offer an approach to other asymptotics. For the case of all unipotent matric
