Bifurcation of plane-to-plane map-germs with corank two of parabolic type
Toshiki Yoshida, Yutaro Kabata, Toru Ohmoto
We study a moduli stratum of A-orbits of plane-to-plane germs of corank 2 with codimension 3. We describe explicitly the bifurcation diagram of its topologically A-versal unfolding…
-triangulations of semialgebraic sets
Toru Ohmoto, Masahiro Shiota
We show that every semialgebraic set admits a semialgebraic triangulation such that each closed simplex is differentiable. As an application, we give a straightforward defini…
Projective classification of jets of surfaces in 3-space
Hiroaki Sano, Yutaro Kabata, Jorge Luiz Deolindo Silva +1
We present a local classification of smooth projective surfaces in 3-space via projective transformations in accordance with singularity types of central projections up to codimens…
