Abstract

We prove a formula for the expected euler characteristic of excursion sets of random sections of powers of an ample bundle (L,h)(L,h), where hh is a Hermitian metric, over a K\"{a}hler manifold (M,ω)(M,\omega). We then prove that the critical radius of the Kodaira embedding ΦN:M\CPn\Phi_N:M\rightarrow \CP^n given by an orthonormal basis of H0(M,LN)H^0(M,L^N) is bounded below when NN\rightarrow \infty. This result also gives conditions about when the preceding formula is valid.
