Abstract:
The Steenrod algebra can not be realized as an
enveloping of any Lie superalgebra. We list several problems that
suggest a need to modify the definition of the enveloping algebra,
for example, to get rid of certain strange deformations which we
qualify as an artifact of the inadequate definition of the
enveloping algebra in positive characteristic. P.Deligne appended
our paper with a realization the Steenrod algebra as a supergroup
scheme,
his comments, hints and open problems.
