摘要: A Švec[1] obtained some results on surfaces in B³by the method of quasi-analytic function. This paper gives several global properties on closed surfaces with qenus zero by the similar method, obtains the main result that a closed special Weingartan surface with qenus zero in E³is a sphere,gives two conditions for two surfaces with congrence property,and proves that there is not closed Bonnet surface with qenus zero.
