Lower bound on the radii of circular orbits in the extremal Kerr black-hole spacetime
Abstract It is often stated in the physics literature that maximally-spinning Kerr black-hole spacetimes are characterized by near-horizon co-rotating circular geodesics of radius $$r_{\text {circular}}$$ rcircular with the property $$r_{\text {circular}}\rightarrow r^+_{\text {H}}$$ rcircular→rH+ ,...
