Abstract
It is shown that, for certain second-order linear homogeneous partial differential equations, there exists a set of equivalence transformations to the form Δ2u+c′(x)u = 0 in the metric of spaces conformal to the space Vn related to the equation. An element of this space is a transformation of the equation to the canonical form
in the metric of a space V′n, where R is the scalar curvature of V′n. Examples are examined of equations reducible to canonical form in spaces of constant curvature and in Kagan's subprojective space. The bibliography contains five references.
