We show that the weak regularization $K_n$ of Dinh and Sibony for the diagonal $\\Delta_Y$ (see Section 2 for more detail) is compatible with wedge product in the following sense: If $T$ is a positive $dd^c$-closed $(p,p)$ current and $\\theta$ is a smooth $(q,q)$ form then there is a sequence of positive $dd^c$-closed $(p+q,p+q)$ currents $S_n$ whose masses converge to 0 so that $-S_n\\leq K_n(T\\wedge \\theta)-K_n(T)\\wedge \\theta \\leq S_n$ for all $n$. We also prove a result concerning the quasi-potentials of positive closed currents. We give two applications of these results. First, we prove a corresponding compatibility with wedge product for the pullback operator defined in our previous paper. Second, we define an intersection product for positive $dd^c$-closed currents. This intersection is symmetric and has a local nature.", "revisions": [ { "version": "v1", "updated": "2011-11-01T19:20:33.000Z" } ], "analyses": { "subjects": [ "37F99", "32H50" ], "keywords": [ "applications", "quasi-potentials", "wedge product", "closed currents", "weak regularization" ], "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1111.0278T" } } }
