Cosmological singularities and analytical solutions in varying vacuum cosmologies
Abstract We investigate the dynamical features of a large family of running vacuum cosmologies for which $$\Lambda $$ Λ evolves as a polynomial in the Hubble parameter. Specifically, using the critical point analysis we study the existence and the stability of singular solutions which describe de-Si...
