The rational topology of gauge groups and of spaces of connections
Svjetlana Terzic
Let P be a principal bundle with semisimple compact simply connected structure group G over a compact simply connected four-manifold M. In this note we give explicit formulas for t…

On rational homotopy of four-manifolds
S. Terzic
We give explicit formulas for the ranks of the third and fourth homotopy groups of all oriented closed simply-connected four manifolds in terms of their second Betti numbers. We al…
