Abstract: Oleg Viro introduced an invariant of rigid isotopy for real algebraic knots and links in $$\mathbb {RP}^3$$RP3 which is not a topological isotopy invariant. In this paper we study real algebraic links of degree d…

Abstract: For a real algebraic link in $RP^3$, we prove that its encomplexed writhe (an invariant introduced by Viro) is maximal for a given degree and genus if and only if its self-linking number with respect…

Abstract: Abstract We extend classical results on the localization of zeros of real univariate polynomials to the localization of zero sets of real multivariate polynomials P, more precisely, of real algebraic hypersurfaces (assuming 0 is a…

Abstract: Let $\mathcal{X}$ be a complex projective manifold of dimension $n$ defined over the reals and let $M$ denote its real locus. We study the vanishing locus $Z\_{s\_d}$ in $M$ of a random real holomorphic section…
