| Abstract: | Let ๐ be a perfect commutative unital ring without zero divisors of char(๐ ) = ๐ and let ๐บ be a multiplicative abelian group. Then the Warfield p-invariants of the normed unit group ๐ (๐ ๐บ) are computed only in terms of ๐ and ๐บ. These cardinal-to-ordinal functions, combined with the Ulm- Kaplansky p-invariants, completely determined the structure of ๐ (๐ ๐บ) when- ever ๐บ is a Warfield ๐-mixed group. |
