Let K be a CW-complex. A map f : X β†’ Y of compacta X and Y is said to be of e-dim K if e-dim f -1 (y) K for every y ∈ Y . We prove that if e-dim f K then there exists a Οƒ -compact subset A of X such that e-dim A K and f | X\A is 0-dimensional. This result is an analogue for extensional dimension of
