Let $M$ be a simply connected complex manifold (of dimension greater than one), $L$ a line bundle, and $\Delta$$\nabla$ a connection on $L$ with possibly singularities along a divisor $D$. We define the curvature as $$ R_{\Delta}(X,Y)=[\Delta_X,\Delta_Y]-\Delta_{[X,Y]} $$$$ R_{\nabla}(X,Y)=[\nabla_X,\nabla_Y]-\nabla_{[X,Y]} $$
Suppose that a second connection $\Delta'$$\nabla'$ on $L$ has the same singularities and the same curvature. Is $\Delta$$\nabla$ equal to $\Delta'$$\nabla'$?
