Complexity factor for black holes in the framework of the Newman–Penrose formalism

Anisotropic stars made of exotic matter within the complexity factor formalism

“…However, the real value of such definition becomes evident when we use it as a supplementary condition to close the set of differential equations of a self-gravitational system. What is more, the complexity factor could be used as a self-consistent way to incorporate anisotropies [68,69], see also [70][71][72][73][74][75][76][77] and references therein.…”

Anisotropic stars made of exotic matter within the complexity factor formalism

“…However, the real value of such definition becomes evident when we use it as a supplementary condition to close the set of differential equations of a self-gravitational system. Additionally, the complexity factor may serve as a self-consistent method for integrating anisotropies [68,69], which has been explored in recent studies [70][71][72][73][74][75][76][77] and their associated references.…”

Stellar models with like-Wyman IIa complexity factor

“…In particular, the complexity criteria is a cutting-edge instrument that enables us to create new anisotropic solutions, as a result of which new solutions have recently been found given the use of this factor in [90][91][92][93][94][95][96][97][98][99][100][101][102][103]. But also, this definition is so adequate that it has allowed to carry out, its implementation on the study of black holes in the framework of the Newman-Penrose formalism [104], construct traversable wormholes geometries [105,106], an study of the departure from spheroidicity of self-gravitating spheres [107], its extension for the time dependent case [108], the study of the dynamics of the gravitational collapse of a compact object [109], for study of axially symmetric systems [110,111], for the study of cylindrical fluid systems [112][113][114], even it has been used in the study of symmetric hyperbolical fluids [115][116][117][118][119][120][121][122][123][124][125][126][127][128], among others. This paper is organized as follows: In Sect.…”
