چکیده
In this note we present an application of the Schwarzian derivative. By exploiting some properties of the Schwarzian derivative, we solve the equation appearing in the gravity-dilaton-antisymmetric tensor system. We also mention that this method can also be used to solve some other equations. The Schwarzian derivative appears naturally in the transformation law of the two-dimensional stress-energy tensor [1]: (∂zz ) T ′(z′) = T (z)− c 12 {z, z}, (1) where {z′, z} denotes the Schwarzian derivative: S(g) ≡ (
