TY - JOUR AU - Ros Mulero, Antonio PY - 2021 UR - http://hdl.handle.net/10481/76582 AB - For any compact Riemannian surface of genus three (Σ,ds2) Yang and Yau proved that the product of the first eigenvalue of the Laplacian λ1(ds2) and the area Area(ds2) is bounded above by 24π. In this paper we improve the result and we show that... LA - eng TI - On the first eigenvalue of the laplacian on compact surfaces of genus three DO - 10.2969/jmsj/85898589 ER -
