For simple algebraic groups of rank 2 defined over algebraically closed fields, we show that the minimal dimension of a closed epimorphic subgroup is 3.Physical SciencesSimple Linear Algebraic GroupEpimorphic SubgroupOn minimal epimorphic subgroups in simple algebraic groups of rank 2text::journal::journal article::research article
