T-duality and exceptional generalized geometry through symmetries of dg-manifolds
Ernesto Lupercio, Camilo Rengifo, Bernardo Uribe
We study dg-manifolds which are R[2]-bundles over R[1]-bundles over manifolds, we calculate its symmetries, its derived symmetries and we introduce the concept of T-dual dg-manifol…

Universal twist in Equivariant K-theory for proper and discrete actions
Noe Barcenas, Jesus Espinoza, Michael Joachim +1
We define equivariant projective unitary stable bundles as the appropriate twists when defining K-theory as sections of bundles with fibers the space of Fredholm operators over a H…
