Abstract: (submitter)

This research is intended to humbly contribute to the vast cosmological scientific knowledge. The main problem considered is studying the manifestation of dark energy and the majestic black holes over spacetime. We work within the research line with the Einstein equations in combination with the scale factor a (t) related to the accelerated expansion of the universe. This model is applied to the physical case of a static unloaded black hole surrounded by quintessence. The interaction of the black hole with the cosmological field of quintessence is put into effect through the direct placement (without the mathematically rigorous obtaining) of the scale factor a (t) in the spatial terms of the geometrical part of the Einstein equations. It is used as the main relatively recent investigative antecedent, the reliable studies carried out on the same problem in [1], where a new spherically-symmetric static solution for a black hole surrounded by quintessence is obtained, using the energy-moment tensor of the equations of Einstein. The Einstein equations of the Theory of General Relativity and its vacuum solutions for a Schwarzschild black hole are used as the main theoretical basis. It also includes a theoretical framework with general aspects of dark energy, and cosmology related to the subject. using the energy-moment tensor of Einstein's equations.
