On quasi-holomorphic homotopies of immersions of 3-manifolds into 5-manifolds
András Csépai
The notion of a quasi-holomorphic homotopy of two immersions of a -manifold into a -manifold extends the notion of their regular homotopy by also allowing the homotopy to pas…

Quasi-holomorphic maps
András Csépai, András Szűcs
We introduce a new notion, called quasi-holomorphic maps. These are real smooth maps equipped with a structure that imitates the singularities and singularity stratifications of ho…

On coincidences of Morin and first order Thom--Boardman singular loci
András Csépai, András Szűcs, Tamás Terpai
It is well-known that the Thom polynomial in Stiefel--Whitney classes expressing the cohomology class dual to the locus of the cusp singularity for codimension- maps and that of…
