    "abstract": "A combined BCDE (Brans-Dicke and Einstein-Cartan) theory with lambda-term is\ndeveloped through Raychaudhuri\u0027s equation, for inflationary scenario. It\ninvolves a variable cosmological constant, which decreases with time, jointly\nwith energy density, cosmic pressure, shear, vorticity, and Hubble\u0027s parameter,\nwhile the scale factor, total spin and scalar field increase exponentially. The\npost-inflationary fluid resembles a perfect one, though total spin grows, but\nthe angular speed does not (Berman, 2007d).
