Non-isometric T-duality from gauged sigma models

Understand

Local symmetries is one of the most successful themes in modern theoretical physics.

• Although they are usually associated to Lie algebras, a gradual increase of interest in more general situations where local symmetries are associated to groupoids and algebroids has taken place in recent years.
• On the other hand, dualities is another persistently interesting theme in modern physics.
• One of the most prominent examples is provided by target space duality in string theory.
