Abstract

Conformal symmetry relates the metric on \$AdS\_2 S^1\$ to that of \$S^3\$. This implies that under a suitable choice of boundary conditions for fields on \$AdS\_2\$ the partition function of conformal field theories on these spaces must agree which makes \$AdS\_2 S^1\$ a good testing ground to study localization on non-compact spaces. We study supersymmetry on \$AdS\_2S^1\$ and determine the localizing Lagrangian for \$N=2\$ supersymmetric Chern-Simons theory on \$AdS\_2S^1\$. We evaluate the partition function of \$N=2\$ supersymmetric Chern-Simons theory on \$AdS\_2 S^1\$ using localization, where the radius of \$S^1\$ is \$q\$ times that of \$AdS\_2\$. With boundary conditions on \$AdS\_2S^1\$ which ensure that all the physical fields are normalizable and lie in the space of square integrable wave functions in \$AdS\_2\$, the result for the partition function precisely agrees with that of the theory on the \$q\$-fold covering of \$S^3\$.
