Principio de Contrastibilidad, Geometr\'ia y Sistemas de Conocimiento

There is a contemporary trend toward geometrizing all mathematical theories, as proposed by the Langlands program, and, by extension, physical theories as well. Within this paradigm, it becomes possible to represent physical objects as formal geometric entities. This opens the door within the framework of logical empiricism pragmatism and constructive realism to the development of a new philosophical approach grounded in a logical mathematical perspective. The aim is to integrate both the physics and metaphysics of the objects of the world into a unified system of knowledge, based on the geometric and physical interpretations of their mathematical representations. This article is presented as a foundational step in the development of that approach.

Compatibilidad del Argumento Cosmol\'ogico Kalam con la Ciencia Contempor\'anea

The Kalam cosmological argument, of a metaphysical nature, asserts that the universe had a first cause. This study examines the compatibility of its premises through a bibliographic review of advancements in contemporary physics. Quantum theory demonstrates that quantum phenomena are indeterministic and non-causal. Even in deterministic theories, causality lacks a clear definition. Moreover, cosmological models, such as cosmic inflation, suggest that the early stages of the universe do not require a first cause. In conclusion, the premises of the Kalam argument are not compatible with contemporary physics.

Exact hairy black holes asymptotically $AdS_{2+1}$

We present a family of $AdS_{2+1}$ asymptotically hairy black holes, within the context of Einstein's minimally coupled scalar field theory. We study the boundary conditions and construct the thermal superpotential. In the Euclidean section, we calculate the free energy and in the Lorentzian section, the Brown-York tensor, both regularized by two methods. Finally, we calculate the relevant thermodynamic quantities and analyze the different phases.
