On the Jacobian polygon and Łojasiewicz exponent of isolated complex hypersurface singularities

Baldur Sigurðsson

Given a hypersurface singularity $(X, 0) \subset (C^{n + 1}, 0)$ defined by a holomorphic function $f : (C^{n + 1}, 0) \to (C, 0)$ , we introduce an alternating ver…

Mixed tête-à-tête twists as monodromies associated with holomorphic function germs

Pablo Portilla Cuadrado, Baldur Sigurðsson

Tête-à-tête graphs were introduced by N. A'Campo in 2010 with the goal of modeling the monodromy of isolated plane curves. Mixed tête-à-tête graphs provide a generalization which d…

The boundary of the Milnor fiber of the singularity f(x,y) + zg(x,y) = 0

Baldur Sigurðsson

Let $f, g \in C {x, y}$ be germs of functions defining plane curve singularities without common components in $(C^{2}, 0)$ and let $Φ (x, y, z) = f (x, y) + z g (x, y)$ . We giv…
