Hajime Ishihara- Constructive Reverse Mathematics- An Introduction and Recent Results
Explore constructive reverse mathematics (CRM) in this comprehensive lecture by Hajime Ishihara. Delve into the classification of theorems in intuitionistic, constructive recursive, and classical mathematics using logical principles and function existence axioms. Begin with an overview of classical reverse mathematics, including the Friedman-Simpson program, before examining axioms of intuitionistic and constructive recursive mathematics. Investigate CRM results with and without countable choice, and discover recent developments in the field. Learn about key concepts such as omniscience principles, Markov's principle, and the relationship among various mathematical principles. Gain insights into the multi-dimensional nature of CRM and its implications for mathematical foundations.
