Resumen: | Let 饾憛 be a perfect commutative unital ring without zero divisors of char(饾憛) = 饾憹 and let 饾惡 be a multiplicative abelian group. Then the Warfield p-invariants of the normed unit group 饾憠 (饾憛饾惡) are computed only in terms of 饾憛 and 饾惡. These cardinal-to-ordinal functions, combined with the Ulm- Kaplansky p-invariants, completely determined the structure of 饾憠 (饾憛饾惡) when- ever 饾惡 is a Warfield 饾憹-mixed group. |
