Scattering matrix in external field problems

E. Langmann, J. Mickelsson

We discuss several aspects of second quantized scattering operators $S^$ for fermions in external time dependent fields. We derive our results on a general, abstract level havi…

Descent equations of Yang--Mills anomalies in noncommutative geometry

Edwin Langmann

Consistent Yang--Mills anomalies $\int\om_{2n-k}^{k-1}$ ( $n \in N$ , $k = 1, 2, \dots, 2 n$ ) as described collectively by Zumino's descent equations $δ\om_{2n-k}^{k-1}+\dd\om_{2n-k-1}^…
