Abstract

We begin by defining a type of K\"ahler metric near the zero section of a trivial holomorphic open disk bundle NN over a compact K\"ahler manifold XX by incorporating flows generated by holomorphic vector fields on XX. These metrics are then shown to deviate exponentially from Poincar\'e-type metrics on NXN\setminus X in terms of the log-polar distance from XX in NN. Lastly we see that they arise naturally when perturbing classes containing Poincar\'e-type K\"ahler metrics of constant scalar curvature to obtain nearby cscK metrics even when the perturbed class on XX does not admit a cscK metric.
