Properties Preserved under Algebraic Constructions
The study of properties of algebras belongs equally to Algebra and to Metamathematics. But here we consider only questions that concern all abstract algebras, and we attempt to discuss them without invoking any unfamiliar metamathematical machinery. In consequence, we can not do justice to the many interesting matters that concern important special classes of algebraic systems, nor to the broad...
متن کاملProperties Preserved under Morita Equivalence of C
We show that important structural properties of C∗-algebras and the multiplicity numbers of representations are preserved under Morita equivalence.

We show that important structural properties of C∗-algebras and the multiplicity numbers of representations are preserved under Morita equivalence.
متن کاملConjunctive languages are closed under inverse homomorphism
It is proved that the inverse homomorphic image of every language generated by a conjunctive grammar can be generated by a conjunctive grammar as well, and, given an arbitrary grammar G over an alphabet Γ and a homomorphism h : Σ∗ → Γ∗, a grammar for the language h−1(L(G)) ⊆ Σ∗ can be effectively constructed. Together with the known results on conjunctive grammars, this implies that the languag...
