On the Notion of Noncommutative Submanifold

We review the notion of submanifold algebra, as introduced by T. Masson, and discuss some properties and examples. A submanifold algebra of an associative algebra is a quotient algebra such that all derivations of can be lifted to . We will argue that in the case of smooth functions on manifolds,...

description We review the notion of submanifold algebra, as introduced by T. Masson, and discuss some properties and examples. A submanifold algebra of an associative algebra is a quotient algebra such that all derivations of can be lifted to . We will argue that in the case of smooth functions on manifolds, every quotient algebra is a submanifold algebra, derive a topological obstruction when the algebras are deformation quantizations of symplectic manifolds, present some (commutative and noncommutative) examples and counterexamples.

I would like to thank Alessandro De Paris for suggesting Example 17 and Chiara Esposito for her comments on a preliminary version of the paper. A special thanks goes to the anonymous referees for carefully reading the paper and suggesting some interesting future research lines.
