Query: Aspects of the polynomial affine model of gravity in three dimensions   The polynomial affine gravity is a model that is built up without the
explicit use of a metric tensor field. In this article we reformulate the
three-dimensional model and, given the decomposition of the affine connection,
we analyse the consistently truncated sectors. Using the cosmological ansatz
for the connection, we scan the cosmological solutions on the truncated
sectors. We discuss the emergence of different kinds of metrics.
