Remarks on the Tripos to Topos Construction

Fabio Pasquali (UU)

Abstract: One of the most relevant construction one meets in dealing with the theory of triposes is the procedure of building an elementary topos out of a given tripos, namely the "tripos to topos Construction (TTC)". In this seminar I will discuss the role of extensionality, comprehension, quotients and functional relations in TTC.
