Pujals Wed, 1 Feb 2017 20:00:00 GMT http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=13882 Equational theories of unstable involution semigroups http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=13882 unstable in the sense that the varieties they generate contain semilattices with nontrivial involution. Specifically, it is shown that the equational theory of an unstable involution semigroup is not finitely axiomatizable whenever the equational theory of its semigroup reduct satisfies the same property. Consequently, many results on equational properties of semigroups can be converted into results applicable to involution semigroups. ]]> Edmond W. H.

Using results on the Effros-Hahn conjecture, we show that an almost amenable, Hausdorff, second countable groupoid is Fredholm. Many groupoids, and hence many pseudodifferential operators appearing in practice, fit into this framework. In particular, one can use these results to characterize the Fredholm operators on manifolds with cylindrical and poly-cylindrical ends, on manifolds that are asymptotically Euclidean or asymptotically hyperbolic, on products of such manifolds, and on many other non-compact manifolds. Moreover, we show that the desingularization of groupoids preserves the class of Fredholm groupoids. ]]> Catarina Carvalho, Victor Nistor and Yu Qiao Wed, 1 Feb 2017 20:00:00 GMT http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=14486 On matrix wreath products of algebras http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=14486 Adel Alahmadi, Hamed Alsulami, S.K.
