Immersions of graphs into projective plane
M. A. Ivashkovsky Lomonosov Moscow State University, Faculty of Mechanics and Mathematics
Abstract:
Immersions of graphs to the projective plane are studied. A classification of immersions up to regular homotopy is obtained. A complete invariant of immersions up to regular homotopy is constructed. The case of graphs immersions to any compact surface different from the projective plane was known.
Key words:
regular immersion of a graph, regular homotopy of immersions, Reidemeister moves, self-intersection number.
