Mirqāt The Ascent of Logic

Contemporary · a field of logic

Cutting-Edge Research

Reverse mathematics, proof mining, homotopy type theory, descriptive complexity: where the field is being written now.

The problem
Exactly which axioms does a given theorem need, and can foundations themselves be made computational?
The turning point
The univalence axiom: equivalent structures are equal, making homotopy type theory a computational foundation.
An open question
Will univalent foundations, reverse mathematics, and proof mining reshape what we take “foundations” to mean?
