One which would take up Morita equivalence as an aspect of a 3-groupoid, as well as Lurie’s claim “The notion of Morita equivalence is most naturally formulated in the language of classifying ∞-topoi” (DAG V). I see there are also suggestions of Morita equivalence accounting for some string dualities, such as here. 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 .

Equivalence and duality: adjoint functors-- categories equivalent to act - S Morita equivalence of monoids-- endomorphism monoids of generators-- on morita duality. (source: Nielsen Book Data) Summary A discussion of monoids, acts and categories with applications to wreath products and graphs. 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.

Se-Jin Kim (). Strong Morita Equivalence and Imprimitivity Theorems. UWSpace. 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.

In order to show precisely how these two well-known criteria are related to one another, we investigate an intermediate criterion called Morita equivalence.

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 In this chapter we introduce Morita duality. Roughly speaking, these theorems are dual to the Morita theorems on category equivalence (Chapter 12).

It was shown by Connes, Douglas, Schwarz[1] 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 [1] for two-dimensional by: Japanese mathematician Kiiti Morita is known for having stated and proved a theorem which gave an equivalent condition for this equivalence in an inﬂuential paper, [Mor58].

This theorem plays an important role in modern algebra, and in his honour, this equivalence of module categories between two rings has been dubbed “Morita.

BMRS08 discusses an axiomatic definition of topological T-duality generalizing and refining T-duality between noncommutative spaces in terms of Morita equivalence to a special type of KK-equivalence, which defines a T-duality action that is of order two up to Morita equivalence.

Alongside with Morita equivalence one considers Morita duality, relating some subcategories of the categories of left $R$-modules and right $S$-modules (mostly the subcategories of finitely-generated modules). However, the very existence of such a duality places definite restrictions on. Abstract: 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).

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.
