摘要:
It is shown that the category CRng-1, of all commutative rings with identity, together with all the ring homomorphisms that preserve the identity, has no proper monoreflective subcategories.

摘要:
The notion of gentle algebra was introduced by I.Assem and A.Skowroński in [4] when classifying the iterated tilted algebras of type.We classify the tilted gentle algebras and give an easy combinatorial condition allowing to verify whether a gentle algebra is tilted or not.

摘要:
For ⋀ a finite dimensional local algebra with radicalNwhereNn= 0 ≠Nn-1define(as a right A-module), thenA(⋀) is quasi-hereditary and it has a unique heredity idealJ1(A).Assume ⋀ satisfies the right socle condition (the socle series and the radical series of ⋀⋀coincide). We show that then the algebraAi/J1(Ai-1) is isomorphic toAi-1whereAi=A(⋀/Ni). for 1 ≤ i ≤ n. Moreover we determine the canonical module forA(⋀) and we show that the Ringel dual ofA(⋀) is isomorphic to the endomorphism ring ofas a left module, provided that ⋀ also satisfies the left socle condition.
