Title: The A’Campo Space in Logarithmic Geometry

Speaker: Marta Aldasoro Rosales 

Abstract: The A’Campo space was originally introduced by N. A’Campo to study the topology of complex hypersurface singularities and their Milnor fibrations. More recently, Fernández de Bobadilla and Pełka extended this construction to the symplectic setting and used it to prove the multiplicity version of Zariski’s conjecture.

In this talk, we present a generalization of the A’Campo space to the setting of fine log analytic spaces. Using the ghost sheaf and the Kato–Nakayama space, we give a global and intrinsic construction that extends the classical one.

Our main result establishes the functoriality of this construction for a suitable category of fine log analytic spaces and exact, vertical morphisms. In particular, we obtain a functor from this category to the category of topological manifolds with boundary and continuous maps.
