CR mappings and their holomorphic extension
Critical sets of 2-dimensional compact manifolds.
Critical values lie on a line.
Curves and surfaces in hyperbolic space
In the first part (Sections 2 and 3), we give a survey of the recent results on application of singularity theory for curves and surfaces in hyperbolic space. After that we define the hyperbolic canal surface of a hyperbolic space curve and apply the results of the first part to get some geometric relations between the hyperbolic canal surface and the centre curve.
Cycles and measure of bifurcation sets for two-dimensional diffeomorphisms.
Cylindrical contact homology of subcritical Stein-fillable contact manifolds.
