*On the local moduli space of locally homogeneous affine connections in plane domains *

Comment.Math.Univ.Carolinae 44,2 (2003) 229-234. **Abstract:**Classification of locally homogeneous affine connections in two dimensions is a nontrivial problem. (See [5] and [7] for two different versions of the solution.) Using a basic formula by B. Opozda, [7], we prove that all locally homogeneous torsion-less affine connections defined in open domains of a 2-dimensional manifold depend essentially on at most 4 parameters (see Theorem 2.4).

**Keywords:** two-dimensional manifolds with affine connection, locally homogeneous connections

**AMS Subject Classification:** 53B05, 53C30
