Fiberings of jets and varieties over algebras. II. (Russian) Zbl 0666.58001
This paper continues the study began by the author [ibid. 15, 98-115 (1983; Zbl 0556.58002)] of fibrations of $$A$$-jets over differentiable manifolds, where $$A$$ is a local algebra over the field of reals. This concept has quite a lot in common with the concept of infinitely close points as introduced by A. Weil. Included in the study are now Lie algebra structures on such fiberings, their transformation properties as well as a kind of second order fiberings.
