Transfer of abelian model structures to equivariant categories and homotopy squares

Zhenxing Di, Liping Li, Li Liang +2

Let $G$ be a finite group acting on a Grothendieck category $A$ with enough projectives, such that $∣ G ∣$ is invertible in $A$ . We prove a general lifting theore…

On silting complexes associated to n-silting modules

Michal Hrbek, Jiangsheng Hu, Rongmin Zhu

We show that any (n+1)-term silting complex whose intermediate cohomology vanishes gives rise to an n-silting module, as recently introduced by Mao. Specializing to commutative noe…

The Waring Problem of Harmonic Polynomials

Hua-Lin Huang, Yilun Tang, Yu Ye +1

This paper investigates the Waring problem of harmonic polynomials. By characterizing the annihilating ideal of a homogeneous harmonic polynomial, i.e., a real binary form that is…

G-dimensions for DG-modules over commutative DG-rings

Jiangsheng Hu, Xiaoyan Yang, Rongmin Zhu

We define and study a notion of G-dimension for DG-modules over a non-positively graded commutative noetherian DG-ring $A$ . Some criteria for the finiteness of the G-dimension of a…

Gorenstein and duality pair over triangular matrix rings

Haiyu Liu, Rongmin Zhu

Let $A$ , $B$ be two rings and $T = (A 0 M B)$ with $M$ an $A$ - $B$ -bimodule. We first construct a semi-complete duality pair…

Recollements induced by left Frobenius pairs

Yajun Ma, Dandan Sun, Rongmin Zhu +1

Given a right exact functor from an abelian category into another abelian category, there is an associated abelian category called the comma category of the functor. In this paper,…

Gluing compactly generated t-structures over stalks of affine schemes

Michal Hrbek, Jiangsheng Hu, Rongmin Zhu

We show that compactly generated t-structures in the derived category of a commutative ring $R$ are in a bijection with certain families of compactly generated t-structures over th…

Gluing and lifting exact model structures for the recollement of exact categories

Jiangsheng Hu, Haiyan Zhu, Rongmin Zhu

In this paper, we first provide an explicit procedure to glue together hereditary exact model structures for the recollement of exact categories. To that end, we use the notion of…

Recollements induced by good silting objects

Rongmin Zhu, Jiaqun Wei

Let $U$ be a silting object in a derived category over a dg-algebra $A$ , and let $B$ be the endomorphism dg-algebra of $U$ . Under some appropriate hypotheses, we show that if $U$ i…

Gorenstein Projective Objects in Comma Categories

Yeyang Peng, Rongmin Zhu, Zhaoyong Huang

Let $A$ and $B$ be abelian categories and $F : A \to B$ an additive and right exact functor which is perfect, and let $(\mathbf{F},\ma…

Recollements associated to cotorsion pairs over upper triangular matrix rings

Rongmin Zhu, Yeyang Peng, Nanqing Ding

Let $A$ , $B$ be two rings and $T = (A M 0 B)$ with $M$ an $A$ - $B$ -bimodule. Given two complete hereditary cotorsion pairs $(\math…

Gorenstein flat modules with respect to duality pairs

Zhanping Wang, Gang Yang

Let $X$ be a class of left $R$ -modules, $Y$ be a class of right $R$ -modules. In this paper, we introduce and study Gorenstein $(X, Y)$ -flat…

Gorenstein homological dimensions of modules over triangular matrix rings

Rongmin Zhu, Zhongkui Liu, Zhanping Wang

Let $A$ and $B$ be rings, $U$ a $(B, A)$ -bimodule and $T = (A U 0 B)$ be the triangular matrix ring. In this paper, we chara…
