Abstract |
|
A commutative ring A is called a Baer ring if the annihilator of each element in A is the principal ideal generated by an idempotent. It is shown that the following three conditions on a semiprime commutative ring A with identity are equivalent: (1) A is a Baer ring, (2) the mapping Q → Q ∩ E is a homeomorphism of Min SpecA with the Boolean space of the Boolean algebra E of idempotents in A, (3) Min Spec A is a retract of SpecA. |
