Abstract
It is shown that the currently studied ‘‘string-inspired’’ model for gravity on a line can be formulated as a gauge-invariant theory based on the Poincaré group with central extension—a formulation that complements and simplifies H. Verlinde’s construction based on the unextended Poincaré group.Keywords
