abstract = {<p style="text-align: justify;">In this paper we use the maximum principle and the Hopf lemma to prove
symmetry results to some overdetermined boundary value problems for domains in
the hemisphere or star-shaped domains in $S^n$. Our method is based on finding suitable $P$-functions as Weinberger ([26]).</p>},
