Let E be a vector bundle with two connections ∇=d+A and ∇′=d+A′. Then, I define coupled curvature equations:
dA+A∧A=dA′+A′∧A′
dA+dA′+A∧A′+A′∧A=0
The gauge group acts on these equations. Over the trivial bundle over a Riemann surface, can we act on the metric connections by the gauge group (we take the parts of type (0,1)) to obtain solutions of these coupled equations from any two metric connections?
