Conformally berwald finsler space with special (α, β) -metric

During this paper, we discover the required necessary and sufficient conditions for a Finsler space with the metric L = α − β2/α to be a Berwald space and also to be a Berwald space, where α could be a Riemannian metric and β may be a differential one-form. In the present paper, we study the conformal change of Berwald space with the above mentioned special (α, β)-metric. In Finsler space we see special (α, β)-metrics such as Randers metric, Kropina metric and Matsumoto metric.,etc.
