Outline of Final Research Achievements

I studied various topics related to singularities of differentiable mappings in order to have new knowledge on differential topology. First, I studied immersions (ie maps with no singularities) between smooth manifolds, using (mainly global aspects of) singularity theory, and published two journal articles. Next, I studied fold maps (smooth maps with only "the mildest" singularities called fold singularities), and published two journal articles. Moreover, I published another journal article on a certain transformation of diagrams of classical knots. I also began to study surface-knots in the last year of the program.
