On coincidence of Alday-Maldacena-regularized σ-model and Nambu-Goto areas of minimal surfaces
PACS: 11.25.Tq
Abstract
For the σ-model and Nambu-Goto actions, values of the Alday-Maldacena-regularized actions are calculated on solutions of the equations of motion with constant non-regularized Lagrangian. It turns out that these values coincide up to a factor, independent of boundary conditions.
