  • N=4 Multi-Particle Mechanics, WDVV Equation and Roots 
    Lechtenfeld, O.; Schwerdtfeger, K.; Thürigen, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    We review the relation of N=4 superconformal multi-particle models on the real line to the WDVV equation and an associated linear equation for two prepotentials, F and U. The superspace treatment gives another variant of ...
  • The Noncommutative Ward Metric 
    Lechtenfeld, O.; Maceda, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    We analyze the moduli-space metric in the static non-Abelian charge-two sector of the Moyal-deformed CP1 sigma model in 1+2 dimensions. After carefully reviewing the commutative results of Ward and Ruback, the noncommutative ...
