Construction of bosonic string theory on infinitely curved Anti-de Sitter space
arXiv:hep-th/0304107 · doi:10.1103/PhysRevD.68.066011
Abstract
Free scalar field theory in the sector with a large number of particles can be interpreted as bosonic string theory on anti-de Sitter space of vanishing radius. Different ways of writing the field theory Hamiltonian translate to different ways of reparametrizing the world-sheet sigma coordinate. Adding a mass term in the field theory corresponds to cutting off the warped AdS direction, with cut-off inversely proportional to the mass. The string theory has neither tachyon, nor critical dimension.
