Recently the author has introduced cobordism-like modules induced from generic maps whose codimensions are negative. They are generalizations of cobo…

The Reeb graph of a function on a smooth manifold is the graph obtained as the space of all connected components of inverse images such that the set …

The theory of Morse functions and their higher dimensional versions or fold maps on manifolds and its application to geometric theory of manifolds is…

The Reeb space of a smooth map whose codimension is minus is the space defined as the space of all connected components of inverse images. For generi…

(Co)bordisms of manifolds and maps are fundamental and important objects in algebraic and differential topology of manifolds and related studies were…
