On the projectivity of finitely generated flat modules
Extracta Mathematicae, 2020 In this paper, the projectivity of a finitely generated flat module of a commutative ring is studied through its exterior powers and invariant factors and then various new results are obtained. Specially, the related results of Endo, Vasconcelos, Wiegand,

Late Modern Projectivity and Existentialism
Przeglad Socjologii JakosciowejThe article addresses the issue of the relationship between existentialism and late modern projectivity interpreted in terms of project work and of biographical projectivity. It does so from the perspective of transformations of subjectivity in modernity

Humanities Research and Projectivity: Disciplinary and Interdisciplinary Strategies of Knowledge [PDF]
Ученые записки Казанского университета: Серия Гуманитарные науки, 2016 The paper makes a distinction between the methodological strategies of humanitarian disciplinary and interdisciplinary knowledge. It is alleged that the disciplinary structure of humanities is supported by a rigid connection between the objectivity of ...

Projectivity and flatness over the endomorphism ring of a finitely generated module
International Journal of Mathematics and Mathematical Sciences, 2004 Let A be a ring and Λ a finitely generated A-module. We give necessary and sufficient conditions for projectivity and flatness of a module over the endomorphism ring of Λ.

Rings Whose Pure-Projective Modules Have Maximal or Minimal Projectivity Domain
Journal of New TheoryIn this study, we investigate the projectivity domain of pure-projective modules. A pure-projective module is called special-pure-projective (s-pure-projective) module if its projectivity domain contains only regular modules. First, we describe all rings

Linear and projective connections over a smooth manifold
Дифференциальная геометрия многообразий фигур, 2023 The principal bundles of the first order coframes and the second order coframes, as well as factor bundle of centroprojective (coaffine) coframes are considered.

Curvature tensor of connection in principal bundle of Cartan's projective connection space
Дифференциальная геометрия многообразий фигур, 2019 We considered Cartan's projective connection space with structure equations generalizing the structure equations of the projective space and the condition of local projectivity (this condition is an analogue to the equiprojectivity condition in the ...

Ewing Sarcoma in Infants and Children Under 2 Years of Age: A French Retrospective Study
Pediatric Blood &Cancer, EarlyView.ABSTRACT Ewing sarcoma, the second most common primary bone cancer in children, requires intensive treatment that may lead to significant long‐term sequelae, particularly in infants. We retrospectively analyzed data from 1621 French patients treated between 1988 and 2015 within the EW88/93/97 or EE99 trials, focusing on 17 infants diagnosed before 24 ...
