Abstract
Fractional calculus is a powerful tool for extending concepts of classical physics. The combination of fractional calculus and cosmology is an especially promising strategy to find new insights and answers to actual problems in astronomy and large-scale physics. In this paper, the fractional action-like variational approach, introduced by the author in 2005, is used to investigate some new cosmological features. We discuss in particular a modified cosmological constant from fractional action-like variational approach with perturbed Einstein's gravity, resulting in a dissipative cosmological constant.
Keywords
fractional action-like variational approach; perturbed Einstein gravity; decaying cosmological constant
