Narratives as Projective Techniques Among Psychology Students – A Content Analysis [PDF]

open access: yes, 2010
This study is based on the writing of a short, potentially projective narrative, and sharing it in small peer groups. There is a close relationship between narratives and projection; readers‘ enjoyment may in fact depend on their ability and readiness to

Motions of Curves in the Projective Plane Inducing the Kaup-Kupershmidt Hierarchy [PDF]

open access: yes, 2012
The equation of a motion of curves in the projective plane is deduced. Local flows are defined in terms of polynomial differential functions. A family of local flows inducing the Kaup-Kupershmidt hierarchy is constructed.

The opposite of projectivity by proper classes

open access: yesJournal of Algebra and Its Applications, 2023
In the last decade, two new approaches have been introduced for the analysis of the projectivity of modules. In this paper, the projectivity of modules has been studied with a new approach by using projectively generated proper classes. As an opposite to projectivity, a module [Formula: see text] is said to be [Formula: see text]-indigent if the ...

Indecomposable $K_1$ classes on a Surface and Membrane Integrals

open access: yesComptes Rendus. Mathématique, 2020
Let $X$ be a projective algebraic surface. We recall the $K$-group $K_{1,\mathrm{ind}}^{(2)}(X)$ of indecomposables and provide evidence that membrane integrals are sufficient to detect these indecomposable classes.

On Higher Syzygies of Projective Toric Varieties [PDF]

open access: yes, 2006
Let A be an ample line bundle on a projective toric variety X of dimension n (≥ 2). It is known that the d-th tensor power A⊗d embedds X as a projectively normal variety in Pr := P(H0(X,L⊗d)) if d ≥ n − 1.

Correspondences between convex geometry and complex geometry [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2017
We present several analogies between convex geometry and the theory of holomorphic line bundles on smooth projective varieties or K\"ahler manifolds. We study the relation between positive products and mixed volumes.

On m-ω1-pω+n-Projective Abelian p-Groups

open access: yesDemonstratio Mathematica, 2014
For any non-negative integers m and n, we define the classes of m-ω1-pω+n- projective groups and strongly m-ω1-pω+n-projective groups, which properly encompass the classes of ω1-pω+n-projectives introduced by Keef in J. Algebra Numb. Th. Acad. (2010) and

Chern Classes of Projective Modules [PDF]

open access: yesNagoya Mathematical Journal, 1963
In topology, one can define in several ways the Chern class of a vector bundle over a certain topological space (Chern [2], Hirzebruch [7], Milnor [9], Steenrod [15]). In algebraic geometry, Grothendieck has defined the Chern class of a vector bundle over a non-singular variety.

Bundles over Quantum RealWeighted Projective Spaces

open access: yesAxioms, 2012
The algebraic approach to bundles in non-commutative geometry and the definition of quantum real weighted projective spaces are reviewed. Principal U(1)-bundles over quantum real weighted projective spaces are constructed.
