“…In [DS07], Dobbs and Shapiro examined the commutative minimal extensions of certain non-domains, and (in a certain sense) reduced the study of commutative minimal extensions to extensions of reduced rings. Other aspects of commutative minimal extensions are studied in [PL96], [PPL06], [Sze50], [Aya03], [Dob06], [Dob07], [Pap76], [OM99], [OM01], [OM03], [Ouk06], as well as others. Minimal extensions of arbitrary rings, as well as minimal noncommutative extensions of commutative rings, have received considerably less attention than their commutative counterparts.…”
