name for vector/tensor field only defined in a discrete set of points












0












$begingroup$


I'm looking for the proper way to refer to a finite or countable set of vectors/tensors 'placed' in some manifold.



The closest word I know is field, but that assumes every point in the manifold has a mapping to a vector/tensor, whereas in my case only a set of measure 0 do.



I've found the notion of incomplete vector field, but that seems defined in a subset of positive measure.
