Soliton Theory

  1. Quaternionic KdV Solutions

    This was my Bachelors essay. It is about a noncommutative generalization of the KdV equation, a prototypical example of a completely solvable nonlinear partial differential equation due in part to its admittance of soliton solutions. It is partly expository, although some new results are shown too.


  • I have learned not to take glory in the difficulty of a proof: difficulty means we have not understood. The ideal is to be able to paint a landscape in which the proof is obvious.
