Singularities of improper affine spheres and surfaces of constant Gaussian curvature
Go-o Ishikawa, Yoshinori Machida
We study the equation for improper (parabolic) affine spheres from the view point of contact geometry and provide the generic classification of singularities appearing in geometric…

Infinitesimal deformations and stabilities of singular Legendre submanifolds
G. Ishikawa
We give the characterization of Arnol'd-Mather type for stable singular Legendre immersions. The most important building block of the theory is providing a module structure on the…

Generic singularities of implicit systems of first order differential equations on the plane
A. A. Davydov, G. Ishikawa, S. Izumiya +1
For the implicit systems of first order ordinary differential equations on the plane there is presented the complete local classification of generic singularities of family of its…
