The Topological Susceptibility of the Lattice CP(n-1) Model on the Torus and the Sphere

N. Schultka, M. Müller-Preussker

The topological vacuum structure of the two-dimensional $C{P}^{n-1}$ model for $n=3,5,7$ is studied on the lattice. In particular we investigate the small-volume limit on the t…
