On the simplicity of multigerms
Raúl Oset Sinha, Maria Aparecida Soares Ruas, Roberta Wik Atique
We prove several results regarding the simplicity of germs and multigerms obtained via the operations of augmentation, simultaneous augmentation and concatenation and generalised c…
Liftable vector fields over corank one multigerms
T. Nishimura, R. Oset Sinha, M. A. S. Ruas +1
In this paper, a systematic method is given to construct all liftable vector fields over an analytic multigerm of corank at most one admi…
Classifying codimension 2 multigerms
R. Oset Sinha, M. A. S. Ruas, R. Wik Atique
We generalise the operations of augmentation and concatenations in order to obtain multigerms of analytic (or smooth) maps with $\mathbb…
A-classification of map-germs via K-equivalence
Kevin Houston, Roberta Wik Atique
The classification of map-germs up to the natural right-left equivalence (also known as A-equivalence) is often complicated. Certainly it is more complicated than K-equivalence whi…
Vanishing topology of codimension 1 multi-germs over R and C
Thomas Cooper, David Mond, Roberta Wik Atique
We construct all codimension 1 multi-germs of maps (k^n,T)-->(k^p,0) with n > p-2, (n,p) nice dimensions, k = R or C, by augmentation and concetenation operations, starting from mo…
