# Math Help - simply connected

1. ## simply connected

how do we know that the curve is simply connection, given the curve gamma (t) = sigma (p(t)) where p(t) is a circle.

do we say that since p(t) is simply connected, hence sigma(p(t)) is simply connection hence curve gamma(t) is simply connected?

2. ## Re: simply connected

I suspect that those functions, p and gamma, will have to be continuous so that is true!
