Noncommutative Burgers Equation [PDF]

, 2003
We present a noncommutative version of the Burgers equation which possesses the Lax representation and discuss the integrability in detail. We find a noncommutative version of the Cole-Hopf transformation and succeed in the linearization of it.

Dark Equations [PDF]

Journal of Nonlinear Mathematical Physics, 2001
Observing the Universe, astronomers have concluded that the motion of stars can not be accounted for unless one assumes that most of the mass in the Universe is carried on by a ``dark matter", so far impervious to all attempts at being detected. There is now a similar concept of ``dark energy".
