Multiple points of immersions

Konstantin Salikhov

Given smooth manifolds $V^{n}$ and $M^{m}$ , an integer $k$ , and an immersion $f : V ↬ M$ , we have constructed an obstruction for existence of regular homotopy of $f$ to an i…

On the orientation of graphs

Konstantin Salikhov

In this short notice we give a universal definition of $Z_{2}$ -module $O r (Γ)$ of orientations of a graph $Γ$ and construct a method, by means of which one can easily verify whenever…

Bordism classes of the multiple points manifolds

Konstantin Salikhov

Let $f : V^{n} ↬ M^{m}$ be a smooth generic immersion. Then the set of points, that have at least $k$ preimages is an image of a (non-generic) immersion. If the manifolds $V…
