Metrics of Poincaré type are Kähler metrics defined on the complement of a smooth divisor D in a compact Kähler manifold X which near D are modeled on the product of a smooth metric on D with the standard cusp metric on a punctured disk in the complex plane. In this talk I will discuss an Arezzo-Pacard type theorem for the existence of such metrics on blowups. A key feature is an obstruction which has no analogue in the compact case, coming from additional cokernel elements for the linearisation of the scalar curvature operator. This additional condition is conjecturally related to ensuring the metrics remain of Poincaré type.
