Transfer of abelian model structures to equivariant categories and homotopy squares
Zhenxing Di, Liping Li, Li Liang +2
Let be a finite group acting on a Grothendieck category with enough projectives, such that is invertible in . 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 . Some criteria for the finiteness of the G-dimension of a…
