Krull--Gabriel dimension and Cohen-Macaulay representations

Naoya Hiramatsu, Yuji Yoshino

Let $R$ be a complete Cohen--Macaulay local ring and $Λ$ an $R$ -order. We study the Krull--Gabriel dimension of the functor category $mod C (Λ)$ , wher…

Connections and naïve lifting of DG modules

Saeed Nasseh, Maiko Ono, Yuji Yoshino

In this paper, we generalize the notion of connections, which was introduced by Alain Connes in noncommutative differential geometry, to the differential graded (DG) homological al…

Semi-fiber products of algebras and lifting of complexes

Saeed Nasseh, Maiko Ono, Yuji Yoshino

Let $k$ be a field. In this paper, we define the notion of semi-fiber products of commutative $k$ -algebras and show that the class of such rings contains several classes of commuta…

Tor algebra of local rings with decomposable maximal ideal

Saeed Nasseh, Maiko Ono, Yuji Yoshino

Let $(R, m_{R})$ be a commutative noetherian local ring. Assuming that $m_{R} =$ $I \oplus J$ is a direct sum decomposition, where $I$ and $J$ are non-zero ideals of $R$ ,…

Diagonal tensor algebra and naive liftings

Saeed Nasseh, Maiko Ono, Yuji Yoshino

The notion of naive lifting of DG modules was introduced by the authors in [16,17] for the purpose of studying problems in homological commutative algebra that involve self-vanishi…
