Kakutani: a generalization of Brouwer's fixed-point theorem

Extended Brouwer's fixed-point result to upper-semicontinuous set-valued mappings with nonempty compact convex values on a compact convex domain.

What is recorded here?

Extended Brouwer's fixed-point result to upper-semicontinuous set-valued mappings with nonempty compact convex values on a compact convex domain.

Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.

Scientific scope

The record is Kakutani's sole-author 1941 Duke Mathematical Journal paper and its finite-dimensional hypotheses. It does not absorb later infinite-dimensional extensions, Nash equilibrium or computational fixed-point algorithms.

Read the original work

This English explanation is an editorial reading view. It does not replace the complete original work or certify its science.
