Consider the power series $f(x)=\sqrt{\frac{1-x}{1-x^p}}$ over the algebraic closure of $\mathbb{Q}_p$, defined by $f(0)=1$. Does it have an analytic continuation that converges on a disk of radius greater than 1? I am particuarly interested in the values for Teichmuller representatives $\lambda$, which satisfy $\lambda^q=\lambda$ for some $q=p^r$. Apparently they are related to classical results on Gauss Sums but I couldn't find anything in the literature.
