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 β Y . We prove that if e-dim f K then there exists a Ο -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
This paper introduces a new concept of dimension for partially ordered sets. Dushnik and Miller in 1941 introduced the concept of dimension of a partial order P, as the minimum cardinality of a realizer, (i.e., a set of linear extensions of P whose intersection is P). Every poser has a greedy realiz
