If K/k
is a finite purely inseparable extension of fields, we are interested in the factorizations
of K as a tensor product over
k of intermediates fields of
K/k.
We introduce the notion of e-factorization
that generalizes the notion of modular factorization. Contrary to modular
factorization, K/k
has always an e-factorization and its factors, when their number
is maximum, are quasi-invariants.Received: 4 April 2002 相似文献
