Abstract |
|
A well-known avenue of research in orientable surface topology is to create and enumerate collections of curves in surfaces with certain intersection properties. We look for similar collections of curves in nonorientable surfaces, which are exactly those surfaces that contain a Möbius band. We generalize a construction of Malestein, Rivin and Theran to nonorientable surfaces to exhibit a lower bound for the maximum number of curves that pairwise intersect 0 or 1 times in a generic nonorientable surface. |
