论文摘要
基于Conrad-Gabber-Prasad的工作，该论文涉及特定的伪隔离群体的几何形状，即可以写成的伪造群体的几何形状。我们确定这些群体在分裂时是缩回的理性，并在其PICARD组上给出结果。
Based on the work of Conrad-Gabber-Prasad, the paper deals with the geometry of particular pseudo-semisimple groups, namely those which can be written as quotient of Weil restriction of semisimple groups. We establish that these groups are retract rational when their are split, and give results on their Picard groups.
