Rigidity results for closed vacuum static spaces

open access: yesAIMS Mathematics, 2023
In this paper we studied rigidity results for closed vacuum static spaces. By using the maximum principle, we achieved rigidity theorems under some pointwise inequalities and showed that the squared norm of the Ricci curvature tensor was discrete.

Einstein y la filosofía del siglo XX

open access: yesArbor: Ciencia, Pensamiento y Cultura, 2007
Se analizan las influencias filosóficas que ayudaron a Albert Einstein en la construcción de la teoría de la relatividad especial, y cómo sus opiniones filosóficas cambiaron con el tiempo para adecuarlas al contenido de su física, un rasgo que es ...

Einstein’s boxes [PDF]

open access: yesAmerican Journal of Physics, 2005
At the 1927 Solvay conference, Albert Einstein presented a thought experiment intended to demonstrate the incompleteness of the quantum mechanical description of reality. In the following years, the experiment was modified by Einstein, de Broglie, and several other commentators into a simple scenario involving the splitting in half of the wave function

Depiction of Space-Time Ontological Geometry Based on Mulla Sadra and Einstein’s Epistemological Bases [PDF]

open access: yesJournal of Philosophical Investigations
The purpose of this article is to explain the quality of creation and examine the essence of space-time based on Sadra'i philosophy and its comparison with physical propositions. The present descriptive-analytical article explores two issues. One is from

Beta-almost Ricci solitons on Sasakian 3-manifolds

open access: yesCubo, 2019
In this paper we characterize the Sasakian 3-manifolds admitting β-almost Ricci solitons whose potential vector field is a contact vector field. Among others we prove that a β-almost Ricci soliton whose potential vector field is a contact vector field on
