Abstract

Consider a holomorphic correspondence ff on a compact K\"ahler manifold XX of dimension kk. Let 1qk1\le q\le k be any integer such that the dynamical degrees of ff satisfy dq1<dqd_{q-1}<d_q. We construct the Green currents TcT_c of ff associated with the classes cc belonging to the dominant eigenspace for the action of ff^* on Hq,q(X,R)H^{q,q}(X,\mathbb{R}). We also show that the super-potential of TcT_c is log\log-H\"older-continuous. When ff has simple action on cohomology and its graph satisfies an assumption on the local multiplicity, we prove the exponential equidistribution of all positive closed currents towards the main Green current, i.e., the only one associated to the unique maximal degree dqd_q.
