Existence of real algebraic hypersurfaces with many prescribed components

Michele Ancona

Given a real algebraic variety $X$ of dimension $n$ , a very ample divisor $D$ on $X$ and a smooth closed hypersurface $Σ$ of $R^{n}$ , we construct real algebraic hypersurfac…

On the topology of random real complete intersections

Michele Ancona

Given a real projective variety $X$ and $m$ ample line bundles $L_{1}, \dots L_{m}$ on $X$ also defined over $R$ , we study the topology of the real locus of the complete inters…

Exponential rarefaction of maximal real algebraic hypersurfaces

Michele Ancona

Given an ample real Hermitian holomorphic line bundle $L$ over a real algebraic variety $X$ , the space of real holomorphic sections of $L^{\otimes d}$ inherits a natural Gaussian p…

Random real branched coverings of the projective line

Michele Ancona

In this paper, we construct a natural probability measure on the space of real branched coverings from a real projective algebraic curve $(X, c_{X})$ to the projective line $(\mathbb{…

Critical points of random branched coverings of the Riemann sphere

Michele Ancona

Given a closed Riemann surface $Σ$ equipped with a volume form $ω$ , we construct a natural probability measure on the space $M_{d} (Σ)$ of degree $d$ branched coverings from…

Random sections of line bundles over real Riemann surfaces

Michele Ancona

Let $L$ be a positive line bundle over a Riemann surface $Σ$ defined over $R$ . We prove that sections $s$ of $L^{d}$ , $d ≫ 0$ , whose number of real zero…
