From this it is possible to give a holomorphic interpretation of flat vector bundles over M. The study of definite connections involves both the construction of examples, most notably via hyperbolic geometry, as well as attempts to understand which 4-manifolds admit definite connections.

Volume 52 [1] [2] [3] [4]. In one differentjelle, one can interpret a flat SL 2,C -bundles over M a defining an alternative complex structure on X.

There is a geometric flow which attempts to deform a given definite connection into one which solves a certain Differentiele. This procedure embeds the Chern-Simons theory of M in the holomorphic Chern-Simons theory of X and one may hope to use techniques from one side to solve problems in the other.

Volume 22 [1] [2] [3] [4]. Volume 35 [1] [2] [3] [4]. Their existence is conjecturaly equiavlent to the stability of the underlying polarised variety.

Links with symplectic reduction and with parabolic geometries. We consider the topological complexity both of the image and of the level sets of such maps diffeerentielle it can be measured by topological invariants such as the rank of the co homology, the minimal number of cells in difrerentielle cell decomposition, the minimal number of generators of the fundamental group or the minimal number of critical points of a Morse function.

Given such a connection the corresponding 2-sphere bundle carries a natural symplectic structure. Volume 19 [1] [2] [3] [4].
