The Euler obstruction of a -form on a determinantal singularity
Anne Frühbis-Krüger, Hellen Santana
In this work, we investigate the connections between the local Euler obstruction and the Poincaré-Hopf-Nash (PHN) index of a -form in the setting of determinantal singularities.…
Drawing real plane algebraic curves in OSCAR
Anne Frühbis-Krüger, Michael Joswig, Lars Kastner
We show how the computer algebra system OSCAR can be used to obtain topologically correct or visually pleasing drawings of real plane algebraic curves.
Monomial algebraic and algebroid curves and their Lipschitz saturation over the ground ring
Anne Frühbis-Krüger, Thiago da Silva
In this article, we provide an explicit description of the Lipschitz saturation of a subalgebra over a ring in terms of th…
Determinantal Singularities
Anne Frühbis-Krüger, Matthias Zach
We survey determinantal singularities, their deformations, and their topology. This class of singularities generalizes the well studied case of complete intersections in several di…
Massively parallel computations in algebraic geometry - not a contradiction
Janko Boehm, Anne Frühbis-Krüger, Mirko Rahn
The design and implementation of parallel algorithms is a fundamental task in computer algebra. Combining the computer algebra system Singular and the workflow management system GP…
On discriminants, Tjurina modifications and the geometry of determinantal singularities
Anne Frühbis-Krüger
We describe a method for computing discriminants for a large class of families of isolated determinantal singularities -- more precisely, for subfamilies of -versal f…
