An Affine Linear Solution for the 2-Face Colorable Gauss Code Problem in the Klein Bottle and a Quadratic System for Arbitrary Closed Surfaces

Sostenes Lins, Emerson Oliveira-Lima, Valdenberg Silva

Let $P ˉ$ be a sequence of length $2 n$ in which each element of ${1, 2, ..., n}$ occurs twice. Let $P^{'}$ be a closed curve in a closed surface $S$ having $n$ points of simple aut…
