Metaideals in Commutative Rings
- R. R. Andruszkiewicz
Algebra Colloquium01 Mar 2005
Preview Abstract
New examples of metaideals in commutative rings are constructed. It is proved that metaideals of a commutative ring form a sublattice of the lattice of all subrings, and for any subring A of a commutative ring P, there exists the largest subring Mid_P (A) (called metaidealizer) in which A is a metaideal. Metaidealizers in several cases are described.
