Abstract
The two-dimensional gravity model with a coupling constant Ic = 4 and a van ishing cosmological constant coupled to a nonlinear matter field is investi gated. We found that the classical equations of motion are exactly solvable and the static solutions of the induced metric and scalar curvature can be obtained analytically These solutions may be used to describe the naked si ngularity at the origin.
