# Localization and periodicity in unstable homotopy theory

@article{Bousfield1994LocalizationAP, title={Localization and periodicity in unstable homotopy theory}, author={Aldridge Knight Bousfield}, journal={Journal of the American Mathematical Society}, year={1994}, volume={7}, pages={831-873} }

In this paper, we develop a hierarchy of natural localizations of spaces, called the vn-periodizations for n > 0, which may be used to expose and study periodic phenomena in unstable homotopy theory. These vn-periodizations act less radically than the corresponding homological localizations [2] and respect fibrations to a very considerable extent. A major part of this paper is devoted to developing the general theory of periodizations of spaces, thereby providing a foundation for the study of… Expand

Recent advances in unstable localization

The essentials of localization of 1-connected spaces —or, more generally, nilpotent spaces— at a set of primes P were solidly established between 1970 and 1975. Since then, the monograph by Hilton,… Expand

In telescopic homotopy theory, a space or spectrum X is approximated by a tower of localizations LnX, n ≥ 0, taking account of vn-periodic homotopy groups for progressively higher n. For each n ≥ 1,… Expand
