Homological Pairs on Simplicial Manifolds

In this thesis we study the relation between Chen theory of formal homology connection, Universal Knizh- nik–Zamolodchikov connection and Universal Knizhnik–Zamolodchikov-Bernard connection. In the first chapter, we give a summary of some results of Chen. In the second chapter we extend the notion of formal homology connection to simplicial manifolds. In particular, this allows us to construct formal homology connection on manifolds M equipped with a smooth/holomorphic properly discontinuos group action of a discrete group G. We prove that the monodromy represetation of that connection coincides with the Malcev completion of the group M/G. In the second chapter, we use this theory to produces holomorphic flat connections and we show that the universal Universal Knizhnik–Zamolodchikov-Bernard connection on the punctured elliptic curve can be constructed as a formal homology connection. Moreover, we produce an algorithm to construct such a connection by using the homotopy transfer theorem. In the third chapter, we extend this procedure for the configuration space of points of the punctured elliptic curve. Our approach is very general and it can be used to construct flat connections on more challenging manifolds equipped with a group action. For example it can be used for the configuration space of points of a higher genus Riemann surface
