GPs' records may have little diagnostic validity

Inaccessible set axions may have little consistency strength

The paper investigates inaccessible set axioms and their consistency strength in constructive set theory. In ZFC inaccessible sets are of the form Vκ where κ is a strongly inaccessible cardinal and Vκ denotes the κ th level of the von Neumann hierarchy. Inaccessible sets figure prominently in category theory as Grothendieck universes and are related to universes in type theory. The objective of...

In this study we investigated whether GPs with a higher workload adhere less to guidelines than thos...
