A QUICK INTRODUCTION TO FIBERED CATEGORIES AND
... 1.4. The stack associated to a category fibered in groupoids. To any category X fibered in groupoids over T there is associated a stack X+ over T called the stackification of X. This gives rise to a 2-functor from FibT to StT which is left adjoint to the inclusion of StT in FibT . The construction o ...

On a fuzzy topological structure
... The aim of this section is to "fuzzify" such basic set-theoretic notions as inclusion, equality, intersection and union. Here we essentially use the ideas of Z.Diskin f5]* Let X be a set and let A C X . Then A can be identified with its characteristic function. We shall use the same notation . for t ...

On Glimm`s Theorem for almost Hausdorff G
... A topological space X is quasi-compact if every open cover of X admits a finite subcover. We say that X is locally quasi-compact if every x-neighborhood of X contains a quasi-compact x-neighborhood. Further X is (locally) compact if X is (locally) quasicompact and Hausdorff. If H is a closed subgrou ...
