Özet

In this paper, we investigate anisotropic cosmological solutions within the framework of Born–Infeld-f(R) gravity, a modification of general relativity that incorporates higher-order curvature invariants. Specifically, we focus on the analysis of Bianchi type-I solutions, which provide a valuable framework for studying the evolution of spatial anisotropies in cosmology. By introducing a reconstruction scheme for this model, we explore the behavior of these solutions, analyze various cosmic evolution scenarios, including Starobinsky inflation, de Sitter-like expansion, power-law dynamics, and Big Rip-like evolution. Additionally, we examine the exponential and power-law behavior of the auxiliary metric function to illustrate its impact on the dynamics of cosmic evolution. Our analysis elucidates how the modifications introduced by Born–Infeld-f(R) gravity influence anisotropic dynamics, offering new perspectives on the late-time behavior of the universe and potential future singularities.
