 Conformal transformation of locally dually flat Finsler metrics Bull. Korean Math. Soc. 2019 Vol. 56, No. 2, 407-418 https://doi.org/10.4134/BKMS.b180288Published online March 1, 2019 Laya Ghasemnezhad, Bahman Rezaei Urmia University; Urmia University Abstract : In this paper, we study conformal transformations between special class of Finsler metrics named $\textbf{C}$-reducible metrics. This class includes Randers metrics in the form $F=\alpha + \beta$ and Kropina metric in the form $F=\frac{\alpha^{2}}{\beta}$. We prove that every conformal transformation between locally dually flat Randers metrics must be homothetic and also every conformal transformation between locally dually flat Kropina metrics must be homothetic.
