Abstract

Let \Teig,n\Tei_{g,n} be the Teichm\"uller space of Riemann surfaces of genus gg with nn punctures. It is conjectured that the Teichm\"uller and Carath\'{e}odory metrics agree on a Teichm\"{u}ller disk if and only if all the zeros of the corresponding holomorphic quadratic differential are of even order. The conjecture was proved by Gekhtman and Markovic for \Tei0,5\Tei1,2\Tei_{0,5}\cong \Tei_{1,2}. We confirm the conjecture for \Tei2,0\Tei0,6\Tei_{2,0}\cong\Tei_{0,6}.
