Syllabus

Syllabus:

Homotopy Type Theory (HoTT) is a new approach to the foundations of
mathematics that revealed surprising connections between Martin-Löf's
Intensional Type Theory (ITT) and classical homotopy theory.

First we give an introduction to ITT and a detailed analysis of
Martin-Löf's axiom of path-induction, the elimination axiom for
equality, or path types, which was so difficult to grasp before
Voevodsky's homotopical interpretation of types as spaces, or better as
infinity groupoids. Through this interpretation ITT satisfies a certain
"principle of naturality" that makes its development unexpectedly
smooth. This naturality is preserved in the extension of ITT with
Voevodsky's axiom of univalence, a principle of special strength and
generality, the consequences of which are extensively studied. In the
last part of the course we present important theorems on path spaces of
higher inductive types like the higher circle and the higher spheres.

No prior knowledge of homotopy theory, mathematical logic or category
theory is required, just a working knowledge of basic algebra and topology.
