Suppose we're living in the plane minus (possibly infinitely many) isolated points, which I'll call poles. Intuitively, the following two statements seem reasonable:
- Loops in the plane are homotopic iff their interior contains the same poles.
- Loops in the plane are homotopic iff they are homologous.
Are these statements true? Why and/or why not?
Edit:
I forgot about winding numbers, so I'd like to expand on statement 1: Does it hold if the winding number of each pole is no greater than 1 in absolute value, and the loop does not intersect itself? Same goes for statement 2.
Edit 2:
I asked about the edited version of question 2 separately.
Regarding question 1, even two non-self-intersecting curves that enclose the same sets of points with winding number 1 might not be homotopic:
