我们研究了特征p p中H H李型群嵌入到相同特征的例外代数群G\mathbf｛G｝中的问题。我们排除了H H是P S L 2 \ mathrm类型的情况{PSL}_2。如果G\mathbf｛G｝的子群不包含在G\mathbf｛G｛的任何正维子群中，则它是李原子群。除了几个可能的例外，我们证明了在G\math bf｛｝中不存在李原子群H H，并且给出了关于H H和G\math BF｛G｝的条件。例外情况是P S L 3（3）\mathrm的H H之一{PSL}_3（3），P S U 3（3）\数学{PSU}_3（3），P S L 3（4）\数学{PSL}_3（4），P S U 3（4）\数学{PSU}_3（4），P S U 3（8）\数学{PSU}_3（8），P S U 4（2）\数学{PSU}_4（2），P S P 4（2）′\数学{

On Medium-Rank Lie Primitive and Maximal Subgroups of Exceptional Groups of Lie Type

We study embeddings of groups of Lie type H H in characteristic p p into exceptional algebraic groups G \mathbf {G} of the same characteristic. We exclude the case where H H is of type P S L 2 \mathrm {PSL}_2 . A subgroup of G \mathbf {G} is Lie primitive if it is not contained in any proper, positive-dimensional subgroup of G \mathbf {G} .

With a few possible exceptions, we prove that there are no Lie primitive subgroups H H in G \mathbf {G} , with the conditions on H H and G \mathbf {G} given above. The exceptions are for H H one of P S L 3 ( 3 ) \mathrm {PSL}_3(3) , P S U 3 ( 3 ) \mathrm {PSU}_3(3) , P S L 3 ( 4 ) \mathrm {PSL}_3(4) , P S U 3 ( 4 ) \mathrm {PSU}_3(4) , P S U 3 ( 8 ) \mathrm {PSU}_3(8) , P S U 4 ( 2 ) \mathrm {PSU}_4(2) , P S p 4 ( 2 ) ′ \mathrm {
