Abstract
Let be a symplectic manifold, endowed with a compatible almost complex structure J and the associated metric g . For any p \in {1, 2, ... (dim M)/2} the form is a calibration. More generally, dropping the closedness assumption on , we get an almost hermitian manifold and then is a so-called semi-calibration. We prove that integral cycles of dimension 2p (semi-)calibrated by possess at every point a unique tangent cone. The argument relies on an algebraic blow up perturbed in order to face the analysis issues of this problem in the almost complex setting.
