We give a self-contained exposition of the proof of faithfully flat descent for projectivity of modules. This fills a gap in the proof given in the literature.

### Pure descent for projectivity of modules

In this note, faithfully flat descent for projectivity is generalized to pure descent for projectivity.

### Pure descent for projectivity of modules

In this note, faithfully flat descent for projectivity is generalized to pure descent for projectivity.

### Base change for coherent cohomology in Berkovich geometry

We prove some base change theorems for coherent cohomology in the setting of Berkovich spaces. In this setting, we get a ﬂat base change theorem, and some proper base change theorems that are

### The Mittag-Leffler condition descents via pure monomorphisms

. This notes aims to clarify the proof given by Raynaud and Gruson [6] that the Mittag-Leﬄer property descents via pure rings monomorphism of commutative rings. A consequence of that is that

### Homological Dimensions with Respect to a Semidualizing Complex

In this paper we build off of Takahashi and White's $\mathcal{P}_C$-projective dimension and $\mathcal{I}_C$-injective dimension to define these dimensions for when $C$ is a semidaulizing complex. We

Principal affine open subsets in affine schemes are an important tool in the foundations of algebraic geometry. Given a commutative ring R , R -modules built from the rings of functions on principal

### A Zariski-local notion of F-total acyclicity for complexes of sheaves1

• Mathematics
• 2015
Abstract We study a notion of total acyclicity for complexes of flat sheaves over a scheme. It is Zariski-local—i.e. it can be verified on any open aﬃne covering of the scheme—and for sheaves over a

### DG homological algebra, properties of ring homomorphisms, and the generalized Auslander-Reiten conjecture

This dissertation contains three aspects of my research that are listed as three joint papers with my advisor and a solo paper in the bibliography [56]–[59]. Each paper will be discussed in a

### Finitistic dimensions over commutative DG-rings

. We study the small and big ﬁnitistic projective, injective and ﬂat dimensions over a non-positively graded commutative noetherian DG-ring A with bounded cohomology. Our main results generalize

### Well-Ordered Flag Spaces as Functors of Points

Using Grothendieck’s “functor of points” approach to algebraic geometry, we define a new infinite-dimensional algebro-geometric flag space as a k-functor (for k a ring) which maps a k-algebra R to
