The cosmological dynamics of a quasi-de Sitter model is described in an “Einstein” representation of the modified Jordan theory using a qualitative theory of dynamic systems. An inflationary picture of the expansion is obtained for a range of the dimensionless acceleration parameter from one to zero.
