Intrinsic characteristic classes for a local Lie group
Ender Abadoglu, Ercument Ortacgil
For a local Lie group M we define odd order cohomology classes. The first class is an obstruction to globalizability of the local Lie group. The third class coincides with Godbillo…
Bi-Hamiltonian Structure in Serret-Frenet Frame
E. Abadoglu, H. Gumral
We reduced the problem of constructing bi-Hamiltonian structure in three dimensions to the solution of a Riccati equation in moving coordinates of Serret-Frenet frame. We then show…

Klein geometries, parabolic geometries and differential equations of finite type
Ender Abadoglu, Ercument Ortacgil
We define the infinitesimal and geometric orders of an effective Klein geometry G/H. Using these concepts, we prove i) For any integer m>1, there exists an effective Klein geometry…
