Polynomial Structure of the (Open) Topological String Partition Function
M. Alim, J. D. Laenge
In this paper we show that the polynomial structure of the topological string partition function found by Yamaguchi and Yau for the quintic holds for an arbitrary Calabi-Yau manifo…

From the Dirac Operator to Wess-Zumino Models on Spatial Lattices
A. Kirchberg, J. D. Laenge, A. Wipf
We investigate two-dimensional Wess-Zumino models in the continuum and on spatial lattices in detail. We show that a non-antisymmetric lattice derivative not only excludes chiral f…

Extended Supersymmetries and the Dirac Operator
A. Kirchberg, J. D. Laenge, A. Wipf
We consider supersymmetric quantum mechanical systems in arbitrary dimensions on curved spaces with nontrivial gauge fields. The square of the Dirac operator serves as Hamiltonian.…
