Fundamental Groups and Covering Spaces

The uncomplicated personality of basic teams and protecting areas are offered as compatible for introducing algebraic topology. the 2 issues are taken care of in separate sections. the point of interest is at the use of algebraic invariants in topological difficulties. functions to different components of arithmetic equivalent to genuine research, complicated variables, and differential geometry also are mentioned.

Nonabelian Algebraic Topology: Filtered Spaces, Crossed Complexes, Cubical Homotopy Groupoids

The most topic of this e-book is that using filtered areas instead of simply topological areas permits the improvement of simple algebraic topology by way of greater homotopy groupoids; those algebraic buildings higher replicate the geometry of subdivision and composition than these ordinarily in use.

Conference on Algebraic Topology in Honor of Peter Hilton

This publication, that is the complaints of a convention held at Memorial college of Newfoundland, August 1983, comprises 18 papers in algebraic topology and homological algebra through collaborators and co-workers of Peter Hilton. it truly is devoted to Hilton at the get together of his sixtieth birthday. a number of the themes lined are homotopy concept, $H$-spaces, staff cohomology, localization, classifying areas, and Eckmann-Hilton duality.
