Abstract
Applying methods of nonlinear σ models, we propose an effective Lagrangian of holes in a spin-liquid state based on the Hubbard model. We study some dynamical properties of the holes especially those related to high- superconductivity using the effective Lagrangian. We argue that there is an attractive interaction between holes in the spin-liquid state, at least in the large-N limit.
