Cosmology with an Effective $\Lambda$-Term in Lyra Manifold

Abstract

A cosmological model in Lyra's geometry are studied under the assumption that an effective cosmological term is appeared in the field equations as the result of interaction between the displacement vector field and an auxiliary $\Lambda$ - term. Some exact solutions of the model equations are obtained and preliminary studied for the simplest cases in order to illustrate how such a model works
