Abstract

We prove that the expected area of the amoeba of a complex plane curve of degree dd is less than 3ln(d)2/2+9ln(d)+9\displaystyle{3\ln(d)^2/2+9\ln(d)+9} and once rescaled by ln(d)2\ln(d)^2, is asymptotically bounded from below by 3/43/4. In order to get this lower bound, given disjoint isometric embeddings of a bidisc of size 1/d1/\sqrt{d} in the complex projective plane, we lower estimate the probability that one of them is a submanifold chart of a complex plane curve. It exponentially converges to one as the number of bidiscs grow to ++\infty.
