In mathematics, specifically category theory, a quasitopos is a generalization of a topos. A topos has a subobject classifier classifying all subobjects, but in a quasitopos, only strong subobjects are classified. Quasitoposes are also required to be finitely cocomplete and locally cartesian closed.[1] A solid quasitopos is one for which 0 is a strong subobject of 1.[2] References1. ^{{cite book|url=https://books.google.com/books?id=7Cj9N7ctjl8C&printsec=frontcover|title=Lecture Notes on Topoi and Quasitopoi|last=Wyler|first=Oswald|isbn=978-9810201531|access-date=3 February 2017|year=1991}} 2. ^{{cite journal|url=http://www.sciencedirect.com/science/article/pii/0022404986900770|title=Quasitopoi, logic and heyting-valued models|journal=Journal of Pure and Applied Algebra|volume=42|issue=2|pages=141–164|last=Monro|first=G.P.|date=September 1986|access-date=3 February 2017|doi=10.1016/0022-4049(86)90077-0 | doi-access=free}} External links
