dc.descriptionDensity linear perturbations in Einstein-Cartan two fluid cosmologies where the outer model is an isotropic Friedmann solution with closed model while the inner model is a flat anisotropic Einstein-Cartan (EC) cosmology with shear are computed by taking into consideration superhorizon situations.This situation is in agreement with the present isotropy of the Cosmic Background Radiation where the anisotropic EC model evolves into an isotropic general relativistic model.Galaxy formation is discussed based on this model.Another type of two fluid is considered where the inner solution is a pressureless Kasner type solution while the outer solution is a de Sitter solution with spin and torsion.
