| Research Abstract |
We tried to investigate the following themes or questions with concernig of the finite type submanifolds or biharmonic submanifolds :
(i)Are there the finite type surfaces with given mean curvature H in the family of surfaces of revolution x.(u, v)=(u cos v, u sin v, f(u)) generated by the periodic function z=f(u) ?
(ii)Are there the finite type surfaces with given Gauss curvature K in the family of surfaces of revolution x(u, v)=(u cos v, u sin v, f(u)) generated by the function z=f(u) ?
(iii)Are there the finite type surfaces with constant mean curvature in the family of surfaces ?
(iv)Are there the Willmore surfaces of finite type ?
(v-1)The finite type submanifolds in the space with D` Atri metric.
(v-2)The biharmonic submanifolds in the space with D` Atri metric
We will continue to study in future the following still open conjectures of Prof. Bang-yen Chen
1.To determine all of the finite type surfaces in Eucldean space of dimension 3
(Chen conjectur 1 : The only finite type surfaces in Eucldean space of dimension 3 are the minimal suefaces, spheres and right cylinders.)
2.To determine all of the biharmonic submanifolds in Eucldean space of dimension n
(Chen conjectur 2 : The only in Eucldean space of dimension n (n>3) are the harmonc ones.)
3.To determine all of the biharmonic submanifolds in Minkowsky space of dimension 4.
