Abstract
In a previous paper,
t
-power
N
-variable diagonal approximants were defined. This scheme of approximants with branch points is extended by defining off-diagonal
t
-power
N
-variable approximants; there is some degree of choice in the defining equations. The extent to which the approximants satisfy the basic properties of symmetry, projection and reciprocal covariance is discussed.
