Description: Define a function on topologies whose value is the convergence relation for sequences into the given topological space. Although is typically a sequence (a function from an upperset of integers) with values in the topological space, it need not be. Note, however, that the limit property concerns only values at integers, so that the real-valued function converges to zero (in the standard topology on the reals) with this definition.
