Abstract

Let XX be a compact complex manifold of dimension kk and f:XXf:X \longrightarrow X be a dominating meromorphic map. We generalize the notion of topological entropy, by defining a quantity h(m,l)top(f)h_{(m,l)}^{top}(f) which measures the action of ff on local analytic sets WW of dimension ll with Wfn(Δ)W \subset f^{-n}(\Delta) where Δ\Delta is a local analytic set of dimension mm. We give then inequalities between h(m,l)top(f)h_{(m,l)}^{top}(f) and Lyapounov exponents of suitable invariant measures.
