Perturbative N = 2 Supersymmetric Quantum Mechanics and L-Theory with Complex Coefficients

Research output: Contribution to journalArticlepeer-review


We construct L-theory with complex coefficients from the geometry of 1|2-dimensional perturbative mechanics. Methods of perturbative quantization lead to wrong-way maps that we identify with those coming from the MSO orientation of L-theory tensored with the complex numbers. In particular, the total volume of a space of 1|2-dimensional vacua reads off the signature of a 4k-dimensional oriented manifold.
