<p><strong><span>RESUMEN:</span></strong><strong> </strong><span><strong>Let M be a smooth m-dimensional manifold and let </strong><strong>∇</strong><strong> be a connection on the tangent bundle of M. We say that the pair (M, </strong><strong>∇</strong><strong>) is an <em>affine manifold</em>if </strong><strong>∇</strong><strong> is torsion free, i.e., if </strong><strong>∇</strong><strong>_XY-</strong><strong>∇</strong><strong>_YX=[X,Y] for any pair of vector fields X and Y. If (M,g) is a Riemannian manifold, let </strong><strong>∇</strong><strong><sup>g</sup></strong><strong> be the Levi-Civita connection. Then, (M, </strong><strong>∇</strong><strong><sup>g</sup></strong><strong>) is an affine manifold. Thus, the notion of an affine structure is a generalization of the notion of a Riemannian structure. In these lectures the notions of an affine Killing vector field and an affine gradient Ricci soliton will be defined. These will be examined in the context of homogeneous affine surfaces and the moduli space of homogeneous affine surfaces will be discussed.</strong><strong></strong></span></p>
