A class of naturally generalized special generic maps

Naoki Kitazawa

Special generic maps are generalizations of Morse functions with exactly two singular points on spheres and canonical projections of unit spheres. They restrict the manifolds of th…

Decompositions of manifolds into submanifolds compatible with specific fold maps

Naoki Kitazawa

We present new explicit decompositions of manifolds via so-called fold maps into lower dimensional spaces. Fold maps form a nice class of so-called generic maps, generalizing Morse…

Manifolds admitting special generic maps and their nice generalized multisections

Naoki Kitazawa

We show that manifolds admitting special generic maps also admit nice generalized multisections. Special generic maps are natural generalized versions of Morse functions with exact…

New families of manifolds with similar cohomology rings admitting special generic maps

Naoki Kitazawa

As Reeb's theorem shows, Morse functions with exactly two singular points on closed manifolds are very simple and important. They characterize spheres whose dimensions are not …

Round fold maps into the plane on some -dimensional closed and simply-connected manifolds

Naoki Kitazawa

Round fold maps are smooth maps on closed manifolds which are locally represented as the product maps of Morse functions and identity maps on open disks and whose singularity is re…

Special generic maps into on closed and simply-connected manifolds and information on the cohomology of the manifolds

Naoki Kitazawa

Morse functions with exactly two singular points on spheres and canonical projections of spheres belong to the class of a certain good class of smooth maps: special generic maps. W…
