Let be a finite dimensional commutative nilpotent algebra over a field of prime characteristic . It has been conjectured that ,
where is the subalgebra of generated by , , .
This was proved (by Eggert) in the case in . This result was extended to the noncommutative case in . Not only is this conjecture important in its own right, but it was shown (by Eggert) that a proof of the above conjecture would result in a complete classification of the group of units of finite commutative rings of characteristic with an identity. In this short paper, we obtain a proof of Eggert’s conjecture in the case .
