Classical polymerization of the Bianchi I model with deformed Poisson structure

We study the dynamics of the Bianchi I cosmological model in the presence of both polymer quantization effects and an exponential deformation of the Poisson algebra. Starting from the Hamiltonian formulation, we derive the polymer-deformed equations of motion and analyze their solutions for the contracting branch of the model. In contrast with the undeformed classical dynamics, the exponential deformation with suitable values of deformation parameters produces a noticeably slower evolution of the volume variable and leads to a stabilization of the anisotropy parameters, which remain bounded throughout the evolution. No removal of the initial singularity is observed; however, the deformation significantly modifies the asymptotic behavior, offering a mechanism to suppress anisotropic shear near the singularity. Our results are illustrated through analytic solutions, highlighting the qualitative differences between the standard and the polymer-deformed Bianchi I cosmology.
