Abstract

The goals of the present research project are: 1) To give the classification of the biharmonic surfaces of constant mean curvature in the product spaces of a surface with the real line. 2) To determine examples of totally biharmonic surfaces in 3-manifolds with non-constant sectional curvature. 3) To give an answer to the following question: Is it true that the only manifolds that admit totally biharmonic surfaces are the space forms?
