Criteria for Morin singularities into higher dimensions
Kentaro Saji
We give criteria for Morin singularities into higher dimensions. As an application, we study the number of A-isotopy classes of Morin singularities.

Geometric invariants of cuspidal edges
Luciana F. Martins, Kentaro Saji
We give a normal form of the cuspidal edge which uses only diffeomorphisms on the source and isometries on the target. Using this normal form, we study differential geometric invar…

Intrinsic properties of surfaces with singularities
Masaru Hasegawa, Atsufumi Honda, Kosuke Naokawa +3
In this paper, we give two classes of positive semi-definite metrics on 2-manifolds. The one is called a class of Kossowski metrics and the other is called a class of Whitney metri…
