摘要

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