Morita equivalence and duality.
P. M. Cohn
This book provides a unified approach to much of the theories of equivalence and duality between categories of modules that has transpired over the last 45 years. In particular, during the past dozen or so years many authors (including the authors of this book) have investigated relationships between categories of modules over a pair of rings that are induced by both covariant and. We develop the theory of Morita equivalence for rings with involution, and we show the corresponding fundamental representation theorem. In order to allow applications to operator algebras, we work within the class of idempotent nondegenerate rings.
T-duality in M(atrix) theory has been argued to be realized as Morita equivalence in Yang-Mills theory on a non-commutative torus (NCSYM). Even though the two have the same structure group, they differ in their action since Morita equivalence makes crucial use of an additional modulus on the NCSYM side, the constant Abelian magnetic background. Morita equivalence for W -algebras to non-selfadjoint dual operator algebras. Our theory contains all examples considered up to this point in the literature of Morita-like equivalence in a dual (weak topology) setting. 3 Morita equivalence of dual operator algebras

Morita-equivalence: a topos-theoretic perspective Olivia Caramello Introduction Toposes as bridges Dualities from topos-theoretic ‘bridges’ Topos-theoretic ‘bridges’ from dualities Dualities versus Morita-equivalences Some examples For further reading Topos à l’IHES Duality and Morita-equivalence In this lecture I shall approach the.
In this paper, we begin by reviewing the material necessary to deﬁne Morita equiva-lence, and we examine two classical examples of Morita equivalence.
We then delve into what is now called “Morita theory”, which is in regards to the key theorems of Morita in [Mor58], the results leading up to them, and their immediate consequences. to be Morita equivalent when their module categories are equivalent.
In many cases, we often only care about rings up to Morita equivalence. If this is the case, then given a ring A, we’d like to nd some particularly nice representative of the Morita equivalence class of A.

ELSEVIER Nuclear Physics B [PM] () B Morita equivalence and duality Albert Schwarz 1 Department of Mathematics, University of California, Davis, CAUSA Received 15 July ; accepted 3 August Abstract It was shown by Connes, Douglas, Schwarz [hep-th/] that one can compactify M(atrix) theory on a non-commutative torus To.

of Mathematics, University of California, Davis, CA USA. T-duality in M(atrix) theory has been argued to be realized as Morita equivalence in Yang-Mills theory on a non-commutative torus (NCSYM). Even though the two have the same structure group, they. Focusing on electromagnetic duality, which is a simple example of S-duality in string theory, I will show that the duality fits naturally into at least one framework for assessing equivalence.
T-duality in M(atrix) theory has been argued to be realized as Morita equivalence in Yang-Mills theory on a non-commutative torus (NCSYM). Even though the two have the same structure group, they differ in their action since Morita equivalence makes crucial use of an additional modulus on the NCSYM side, the constant abelian magnetic background.
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We study the notion of Morita equivalence in various categories. We start with Morita equivalence and Morita duality in pure algebra. Then we consider strong Morita equivalence for C*-algebras and Morita equivalence for W*-algebras.
Finally, we look at the corresponding notions for groupoids (with structure) and. It has been a while since I have looked at it but from memory "Morita Equivalence and Duality" by Cohn is quite a nice book and I think it contains several examples (I hope that I am remembering correctly).
The Morita-equivalence between MV-algebras and abelian ℓ-groups with strong unit Olivia Caramello∗ and Anna Carla Russo Ap Abstract We show that the theory of MV-algebras is Morita-equivalent to that of abelian ℓ-groups with strong unit.
This generalizes the well-known equivalence between the categories of set-based models of. This includes a detailed discussion of Morita equivalence of \(C^*\)-algebras, a review of the necessary sheaf cohomology, and an introduction to recent developments in the area.
The book is accessible to students who are beginning research in operator algebras after a. Morita Equivalence Eamon Quinlan Given a (not necessarily commutative) ring, you can form its category of right modules. Take this category and replace the names of all the modules with dots. The resulting category is a bunch of dots with a bunch of arrows.
The question is: what can you then say about the original ring from this category of. In abstract algebra, Morita equivalence is a relationship defined between rings that preserves many ring-theoretic properties.
It is named after Japanese mathematician Kiiti Morita who defined equivalence and a similar notion of duality in Author(s): Schwarz, Albert | Abstract: It was shown by Connes, Douglas, Schwarz that one can compactify M(atrix) theory on noncommutative torus.
We prove that compactifications on Morita equivalent tori are physically equivalent. This statement can be considered as a generalization of non-classical duality conjectured in  for two-dimensional tori.For UHF C*-algebras, any,-equivalence preserves the dimension of the underlying Hilbert space of a repre- sentation, since any representation is a direct sum of representations with under- lying, separable, infinite dimensional Hilbert spaces; and direct sums are preserved by .
