On train algebras of rank 3
First, the author recalls some concepts introduced in his preceding paper [cf. Proc. Edinb. Math. Soc., II. Ser. 33, No.1, 61-70 (1990; Zbl 0671.17022)]: train algebras of rank 3, the type of such algebras, which is an ordered pair of integers. In section 1 all train algebras of type (n,1) are classified such that dim J\(=\dim B_ 1B_ 2\oplus B_ 2\geq 2\). In section 2 train algebras of type (3,n-2) such that dim J\(=n-1\) are classified. In section 3 all train algebras \(B'\) are considered whose kernel B is anisotropic, that is to say that dim \(B^ 2=1\) and the bilinear form defined by the multiplication has a one-dimensional radical and its regular part is anisotropic.
