WebOur task now is to determine one of the Borel subgroups of GLn(C). We wish to show that all Borel subgroups of GLn(C) are conjugate to the subgroup B of invertible n×n upper triangular matrices over C. To verify this we must show two things: that B is solvable, and that no solvable subgroup of GLn(C) properly contains B.
