17 de sept. de 2016 · This chapter conveys a study of a special class of topological spaces, called CW-complexes introduced by J.H.C. Whitehead (1904–1960) in 1949 with their homotopy properties to meet the need for development of algebraic topology.This class of spaces is broader and has some better categorical properties than simplicial complexes, but still retains a combinatorial nature that allows for ...

It should be said that there is no theoretical obstacle to calculating 7r,(K), for any r > 1, by construictiolns which are similar to those in a combinatorial definition of'6 ri(K). rTIs the value of ?6, below, is technical, rather than theoretical, in that it brings nsew algeobrai
Note on Fibre Spaces. I. James, J. Whitehead. Published 1954. Mathematics. Proceedings of The London Mathematical Society. This chapter presents an assumption where W 2n–1 is the space of unit tangent vectors to the n -sphere S n . Then, W 2n–1 is a fiber bundle over S n , with fiber S n–1 . When n is odd, W 2n–1 has a cross-section and ...
ON THE REALIZABILITY OF HOMOTOPY GROUPS. By J. H. C. WHITEHEAD. (Received June 11, 1948) The object of this note is to prove a theorem, which provides an affirmative answer to the following question, proposed by S. Eilenberg at the Princeton Bicentennial Conference. "Given a (finite or infinite) polyhedron, P, and given r > 1, does there exist ...
