正元

研究了Banach代数与C代数中半序的某些性质，证明了在C代数中，包含正元的乘锥是唯一的，并给出了Banach代数成为C代数的一些充分条件。

Some problems on the partial order in Banach algebras and C-algebras are studied . The uniqueness of the multiplicative cone which contains all the positive elements of the C-algebra is discussed . Conditions of Banach algebras becoming C - algebras are presented .
