A unified geometric description of the Universe: From inflation to late-time acceleration without an inflaton nor a cosmological constant

We present a cosmological model arising from a gravitational theory with an infinite tower of higher-order curvature invariants that can reproduce the entire evolution of the Universe: from inflation to late-time acceleration, without invoking an inflaton nor a cosmological constant. The theory is E...
