Abstract
In this work, we conduct a noncommutative analysis of a Bianchi I model coupled to a reduced relativistic gas. The classical field equations are modified by introducing noncommutativity through a generalized symplectic formalism. We observe that the noncommutative version of this model exhibits several significant differences compared to its commutative counterpart, as it alters the dynamics of the universe's expansion and isotropization.
