Regular unipotent elements from naturally embedded subgroups of rank 2 in modular representations of classical groups

We study images of regular unipotent elements from naturally embedded subgroups of type $A_2$ and $B_2$ in irreducible modular representations of classical groups. For the images of such elements and representations with locally small highest weights one encounters Jordan block of all sizes of the same parity. Bibl. – 17 titles.
