On geometry of sub-Riemannian η-Einstein manifolds
Дифференциальная геометрия многообразий фигур, 2019 On a sub-Riemannian manifold of contact type a connection with torsion is considered, called in the work a Ψ-connection. A Ψ-connection is a particular case of an N-connection.

Social investment agenda setting: A personal note
International Journal of Social Welfare, Volume 32, Issue 1, Page 76-85, January 2023., 2023 Abstract This article reconstructs how, under the umbrella of the Europea Union (EU), discreet opportunities for EU social policy agenda setting opened for academic expertise from the late 1990s to the 2020s. This began with the Dutch presidency of the EU in the first half of 1997, endorsing the notion of ‘social policy as a productive factor ...

Decomposition of geometric perturbations
, 2008 For an infinitesimal deformation of a Riemannian manifold, we prove that the scalar, vector, and tensor modes in decompositions of perturbations of the metric tensor, the scalar curvature, the Ricci tensor, and the Einstein tensor decouple if and only if

Bioinspired Nanoscale 3D Printing of Calcium Phosphates Using Bone Prenucleation Clusters
Advanced Materials, EarlyView.This study develops a bone‐bioinspired photoresin containing PNCs of calcium phosphates, enabling nanoscale precision via 2pp. This novel approach allows for 2D patterning and 3D nanostructuring of CaPs with intricate geometries. The technique offers unparalleled control over scaffold design and porosity, paving the way for advanced applications in ...

Modern Theology, Volume 39, Issue 1, Page 19-46, January 2023., 2023 Abstract This essay explores the development of Tillich’s writings on the relationship between divine providence and suffering, and his approach to theodicy. First, I attend to the various stations of his early life and his earliest writings in various genres.

Einstein metrics on tangent bundles of spheres
, 2002 We give an elementary treatment of the existence of complete Kahler-Einstein metrics with nonpositive Einstein constant and underlying manifold diffeomorphic to the tangent bundle of the (n+1)-sphere.Comment: 9 ...

Chemically Reactive Thin Films: Dynamics and Stability
Advanced Materials Interfaces, EarlyView.What happens to a thin liquid film when chemical reactions occur inside it? By means of theoretical analysis, it is showed that such systems (which are very common in heterogeneous catalysis) become very dynamic and not only their wetting properties are strongly affected by the chemical activity, moreover their interface can undergo traveling and ...

A new curvature-like tensor in an almost contact Riemannian manifold
Pracì Mìžnarodnogo Geometričnogo Centru, 2016 In a M. Prvanović’s paper [5], we can find a new curvature-like tensor in an almost Hermitian manifold.In this paper, we define a new curvature-like tensor, named contact holomorphic Riemannian, briefly (CHR), curvature tensor in an almost ...
