Singular vectors and invariant equations for the Schrödinger algebra in n ≥ 3 space dimensions. The general case.

The singular vectors in Verma modules over the Schrödinger algebra ŝ( n) in ( n + 1)-dimensional space-time are found for the case of general representations. Using the singular vectors, hierarchies of equations invariant under Schrödinger algebras are constructed. [ABSTRACT FROM AUTHOR]
