M. Matsumoto proved that any \(2\)-spray is projectively a geodesic spray of a Finsler manifold [Math. Comput. Modelling 20, No. 4–5, 1–23 (1994; Zbl 0812.53022)]. This result was refined, by the first author of this paper and others to the case of constant coefficients sprays, all of which are projectively equivalent to straight lines [Nonlinear Anal. 37, 545–566 (1999)].
In the present paper, the authors classify \(2\)-sprays whose coefficients are linear in \(x^{1}, x^{2}\), (the adapted coordinates), by a perturbation technique. They also study the Feynman-Kac solutions to the corresponding Finslerian diffusions.
