Rigidity of bi-Lipschitz equivalence of weighted homogeneous function-germs in the plane
TL;DR: The main goal of as discussed by the authors is to show that if two weighted homogeneous (but not homogeneous) function-germs are bi-Lipschitz equivalent, then they are analytically equivalent.

Singularities of 3-parameter line congruences in $\mathbb{R}^4$.
TL;DR: In this paper, the singularities of 3-parameter line congruences are classified in terms of the singularity of the Blaschke (affine) normal congruence.

Invariants of Relative Right and Contact Equivalences
TL;DR: In this paper, the authors study holomorphic function germs under equivalence relations that preserve an analytic variety and show that two quasihomogeneous polynomials, not necessarily with isolated singularities, having isomorphic relative Milnor algebras are relative right equivalent.
Line Congruences on singular surfaces
TL;DR: In this article , it was shown that the equation of the principal surfaces is a multiple of the equations of the developable surfaces, and that the multiplicative factor is associated to the singular set of ξ .

Join operation and ${\mathcal A}$-finite map-germs
TL;DR: In this paper, a general form of elementary join maps, called elementary joins, was defined for the purpose of producing new finite map-germs from them. But their main tools are the delta invariant and some invariants of curves.
