Viewing comodule algebras as the noncommutative analogues of affine varieties with affine group actions, we propose rudiments of a localization approach to nonaffine Hopf algebraic quotients of noncommutative affine varieties corresponding to comodule algebras. After reviewing basic background on noncommutative localizations, we introduce localizations compatible with coactions. Coinvariants of these localized coactions give local information about quotients. We define Zariski locally trivial… 
Noncommutative localization in noncommutative geometry
The aim of these notes is to collect and motivate the basic localization toolbox for the geometric study of ``spaces'', locally described by noncommutative rings and their categories of one-sided
Categorified symmetries
Quantum field theory allows more general symmetries than groups and Lie algebras. For instance quantum groups, that is Hopf algebras, have been familiar to theoretical physicists for a while now.
Differential Calculi on Quantum Principal Bundles over Projective Bases
We propose a sheaf-theoretic approach to the theory of differential calculi on quantum principal bundles over non-affine bases. Our main class of examples is given by quantum principal bundles over

Philosophy of quantum groups as Hopf algebras and their actions and coactions on algebras and graded algebras captures only affine and some projective phenomena in noncommutative algebraic geometry.
Compatibility of (co)actions and localizations
Earlier, Lunts and Rosenberg studied a notion of compatibility of endofunctors with localization functors, with an application to the study of differential operators on noncommutative rings and
\v{C}ech cocycles for quantum principal bundles
In other to study connections and gauge theories on noncommutative spaces it is useful to use the local trivializations of principal bundles. In this note we show how to use noncommutative

The theory of modules over associative algebras and the theory of comodules for coassociative coalgebras were developed fairly independently during the last decades. In this survey we display an
