AbstractWe establish a patchworking theoremà laViro for the Log-critical locus of algebraic curves in(ℂ∗)2{(\mathbb{C}^{\ast})^{2}}. As an application, we prove the existence of projective curves of arbitrary degree with smooth connected Log-critical locus. To prove our patchworking theorem, we study the behaviour of Log-inflection points along families of curves defined by Viro polynomials. In particular, we prove a generalisation of a theorem of Mikhalkin and the second author on the tropical limit of Log-inflection points.
