Description
In this work we have discussed the origin of cosmic viscosity with the in of deformed cosmic phase space geometry. We have introduced the Non-Commutative(NC) deformed geometry and shown that the transformation from non-Riemannian geometry to Riemannian geometry (From Non-Commutative to Commutative(C) geometry) can provide the dissipation in cosmology. A single scalar field in deformed Non-Commutative cosmology can be dissociated into two scalar field models due to the transformation from NC-geometry to C-geometry. This dissociation mainly provides the radiation field with an interior viscosity-dependent interaction. Finally, we have provided the nature of phase space and their decomposition during the phase transition from single-field NC-geometry to Multi-field C-geometry.
