From bungee to and Hamiltonian systems and their integrability and nonintegrability
Vladimir DragoviÄ, Borislav GajiÄ, Božidar JovanoviÄ
We consider natural Hamiltonian systems with potentials that are or on a hypersurface and -smooth in the complement and introduce and study corresponding no…

A Lax representation and integrability of homogeneous exact magnetic flows on spheres in all dimensions
Vladimir DragoviÄ, Borislav GajiÄ, Božidar JovanoviÄ
We consider motion of a material point placed in a constant homogeneous magnetic field restricted to the sphere . We provide a Lax representation of the equations of motio…

Complexity of Lasso with Normalized Data, Geometry and Combinatorics
Vladimir DragoviÄ, Vladimir Dragović, Borislav GajiÄ +1
We observe and prove that the complexity of lasso for normalized data is smaller than for nonnormalized ones by relating this question to extremal combinatorics and algebraic graph…
