On metric space valued functions of bounded essential variation

Let ∅≠T ⊂ R and let X be a metric space. For an ideal J ⊂ P(T) and a function f:T-> X, we define the essential variation V Jess(f, T) as the in mum of all variations V (g; T) where g:T-> X, g = f on TE, and E in J. We show that if X is complete then the essential variation of f is equal to inf...
