A natural extension of a homogeneous geodesic in homogeneous Riemannian spaces G/H, known as a two-step homogeneous geodesic, can be expressed in the form γ(t)=π(exp(tx)exp(ty)), where x and y are elements of the Lie algebra of G. This paper aims to expand this concept to homogeneous Finsler spaces. We provide certain sufficient conditions for (α,β) spaces and decomposable cubic spaces to possess a one-parameter family of invariant Finsler metrics that can be classified as two-step Finsler geodesic orbit spaces. Additionally, we present some illustrative examples of these spaces. © The Indian National Science Academy 2025.

In 2002, using a variational method, Lauret classified five-dimensional nilsolitons. In this work, using the algebraic Ricci soliton equation, we obtain the same classification. We show that, among ten classes of five-dimensional connected and simply connected nilmanifolds, seven classes admit the Ricci soliton structure. Furthermore, we compute the derivation that satisfies the algebraic Ricci soliton equation in each case.. © 2024 Iranian Mathematical Society.

In this paper, we give the flag curvature formula of general (α, β)-metrics of Berwald type. We study conformally related (α, β)-metrics, especially general (α, β)-metrics that are conformally related to invariant (α, β)-metrics. Also, a necessary and sufficient condition for a Finsler metric conformally related to an (α, β)-metric is given and conformally related Douglas Randers metrics are studied. Finally, we present some examples of conformally related (α, β)-metrics. © 2024 NISC (Pty) Ltd.
