Quanta Magazine Covers Reverse Mathematics

An article just published in Quanta Magazine by Natalie Wolchover covers a recent result from reverse mathematics.  Keita Yokoyama and Ludovic Patey showed that Ramsey's theorem for pairs is finitistically reducible, i.e., it is $latex \Pi_3$ conservative over $latex I\Sigma_1$. The article explains Ramsey's theorem, but also Hilbert's program and its more recent relativizations, i.e., … Continue reading Quanta Magazine Covers Reverse Mathematics

The orthodox approach to foundations interprets mathematics in the universe of sets. More recently, however, there have been other developments that call into question the whole method … Continue reading CfA: Foundations of Mathematical Structuralism
