Abstract.
Let M be a two-dimensional complex manifold and let \(f:M\to M\) be a holomorphic map that fixes pointwise a (possibly) singular, compact, reduced and globally irreducible curve \(C\subset M\). We give a notion of degeneracy of f at a point of C. It turns out that f is non-degenerate at one point if and only if it is non-degenerate at every point of C. When f is non-degenerate on C, we define a residual index for f at each point of C. Then we prove that the sum of the indices is equal to the self-intersection number of C.
