Singularities of 3-parameter line congruences in $R^{4}$

Débora Lopes, Maria Aparecida Soares Ruas, Igor Chagas Santos

In this paper, we give the generic classification of the singularities of 3-parameter line congruences in $R^{4}$ . We also classify the generic singularities of Blaschke (af…

Join operation and $A$ -finite map-germs

Maria Elenice Rodrigues Hernandes, Maria Aparecida Soares Ruas

In this work we define some map-germs, called elementary joins, for the purpose of producing new $A$ -finite map-germs from them. In particular, we describe a general for…
