On the Generalized Curvature [PDF]
By using methods of nonstandard analysis given by Robinson, A., and axiomatized by Nelson, E., we try in this paper to establish the generalized curvature of a plane curve at regular points and at points infinitely close to a singular point.

Energy Singularity: From Scarcity to Abundance
The ability to extract and use energy played a decisive role in the development of human civilization. Energy consumption is growing exponentially, thus the only way to avoid future energy crisis is to explore renewable, more abundant sources.

Strength of the naked singularity in critical collapse
The critical collapse of a scalar field is a threshold solution of black hole formation, in which a naked singularity arises. We study here the curvature strength of this singularity using a numerical ansatz.

It is advisable to avoid and, even better, demystify such grandiose terms as “infinity” or “singularity” in the description of the cosmos. Its proliferation does not positively contribute to the understanding of key concepts that are essential for an ...

Structural stability of the two-fold singularity [PDF]
At a two-fold singularity, the velocity vector of a flow switches discontinuously across a codimension one switching manifold, between two directions that both lie tangent to the manifold. Particularly intricate dynamics arises when the local flow curves

Physical Processes in Naked Singularity Formation [PDF]
Gravitational collapse is one of the most fruitful subjects in gravitational physics. It is well known that singularity formation is inevitable in complete gravitational collapse. It was conjectured that such a singularity should be hidden by horizons if

Superconformal field theory on threebranes at a Calabi-Yau singularity [PDF]
Just as parallel threebranes on a smooth manifold are related to string theory on AdS5 × S5, parallel threebranes near a conical singularity are related to string theory on AdS5 × X5, for a suitable X5.

The Concept of “Community” in the Social Ontology of J.-L.Nancy and J. Agamben [PDF]
The article discusses new ontological approaches to the concept of “community” that appeared after the “ontological turn”. If ontotheology (metaphysics) in search of the foundation of the existing (society) takes the existing beyond the limits of the ...
