摘要：

In two-dimensional space-time, point particles can experience a geometric, dimension-specific gravity force, which modifies the usual geodesic equation of motion and provides a link between the cosmological constant and the vacuum theta-angle. The description of such a force fits naturally into a gauge theory of gravity based on the extended Poincare group, i.e. ''string-inspired'' dilaton gravity.
