I will report on some joint work with Piotr Achinger, about a \u201cBetti realization\u201d functor for varieties over the formal punctured disk $\\mathsf{Spec}\\mathbb{C}((t))$, i.e. defined by polynomials with coefficients in the field of formal Laurent series in one variable over the complex numbers. We give two constructions producing the same result, and one of them is via \u201cgood models\u201d over the power series ring $\\mathbb{C}[[t]]$ and the \u201cKato-Nakayama\u201d construction in logarithmic geometry, that I will review during the talk.<\/p>\n
