The Brazilians Singularity Theory Webinar of this semester will be dedicated to the memory of Maria Aparecida Soares Ruas (Cidinha). Her trajectory deeply marked the development of Singularity Theory in Brazil and worldwide, training generations of mathematicians and consolidating research groups that today continue her legacy.
This special series will feature talks by her collaborators, who will present results and perspectives related to her contributions, celebrating the strength and vitality of her work.

Abstract: In this lecture, I will present some of the main results in partnership with Professor Maria Aparecida Soares Ruas (Cidinha) in the study of monomial map-germs from (C^n,0) to (C^p,0) for p ≥ 2n, with respect to A-equivalence relation. In these dimensions, we obtain the general form of A-finitely determined (A-finite) monomial map-germs of any corank. Particularly, we classify A-finite monomial map-germs from (C^n,0) to (C^2n,0).
