| Research Abstract |
We studied flat centroaffine surfaces with non-semisimple Tchebychev operator and showed that if the Pick invariant is constant then it is a centroaffine minimal surfaces described by the Meijer G-function. We also regarded centroaffine minimal surfaces, which is a natural generalization of proper affine spheres centered at the origin, as surfaces in the projective space and classified such surfaces whose associated surfaces are projective minimal.
We also studied surfaces in the complexified sphere parametrized by a complexified orthogonal net. Moreover, we introduced the countably infinite number of presymplectic structures on the space of closed equicentroaffine plane curves and showed that such a space can be described by multi-hamiltoninan system.
