In our main result we show that the C*-algebra of a locally compact Hausdorff etale Zappa-Szep product groupoid is a C*-blend, in the sense of Exel, of the individual groupoid C*-algebras. We finish with some examples, including groupoids built from *-commuting endomorphisms, and skew product groupoids.doi:10.1007/s00233-016-9775-...
例4.6: 另一方面,还存在这样的范畴,它的每个态射都是同构。这样的范畴称为群胚(groupoids)。 读者已经知道很多群胚的例子,可以查阅习题4.2。 自同构(automorphism): 范畴 \mathrm{C} 的对象 A 的自同构是从 A 到它自身的同构,记作 \mathrm{Aut}_{\mathrm{C}}(A)。 \mathrm{Aut}_{\mathrm{C}}(A)\...

A detailed study of different notions of product of fuzzy sets in a groupoid is carried out. The ultimate superiority of Liu's set product is established. Level subsets and strong level subsets of these products are also analysed. Consequently, simplified proofs of some of the results on free...

Symplectic reduction is reinterpreted as the composition of arrows in the category of integrable Poisson manifolds, whose arrows are isomorphism classes of dual pairs, with symplectic groupoids as units. Morita equivalence of Poisson manifolds amounts to isomorphism of objects in this category. This ...
