... expresses the genus of Σ a in terms of C a · C a , c1(M)·C a andP ∈(C a )singδ(C a ,P). Sum over a and adjust by the intersections of C a with C a for a = a to deduce (4).As a measure ... general case let F a be the polynomial just obtained for C = C a .PutF (a 0, ,a d)= a Fm a a. The coefficient of sd0has the same zero locus as p∗ (a 0); so after rescaling by a constant, ... suchconfigurations is of real codimension 2d a m a . Therefore Z is a union of sub-manifolds of real codimension at least 2, and these may be avoided in any pathby small perturbations. Apply the...
