Formal geometry and Tamarkin--Tsygan calculi of dg manifolds

Hsuan-Yi Liao, Mathieu Stiénon, Ping Xu

The main goal of this paper is to study the formal geometry of dg manifolds à la Fedosov. For any dg manifold , we construct a Fedosov dg foliation (or dg Lie alg…

Vertical isomorphisms of Fedosov dg manifolds associated with a Lie pair

Hua-Shin Chang, Hsuan-Yi Liao

We investigate vertical isomorphisms of Fedosov dg manifolds associated with a Lie pair , i.e. a pair of a Lie algebroid and a Lie subalgebroid of . The construct…

Differential graded manifolds of finite positive amplitude

Kai Behrend, Hsuan-Yi Liao, Ping Xu

We prove that dg manifolds of finite positive amplitude, i.e. bundles of positively graded curved -algebras, form a category of fibrant objects. As a main step in the…

On the structure of étale fibrations of -bundles

Kai Behrend, Hsuan-Yi Liao, Ping Xu

We prove that an étale fibration between -bundles admits local sections composed of several elementary morphisms of particularly simple and accessible type. As applicatio…

Atiyah classes and Todd classes of pullback dg Lie algebroids associated with Lie pairs

Hsuan-Yi Liao

For a Lie algebroid and a Lie subalgebroid , i.e. a Lie pair , we study the Atiyah class and the Todd class of the pullback dg (i.e. differential graded) Lie algebroi…

Derived Differentiable Manifolds

Kai Behrend, Hsuan-Yi Liao, Ping Xu

We develop the theory of derived differential geometry in terms of bundles of curved -algebras, i.e. dg manifolds of positive amplitudes. We prove the category of deri…

Formal exponential map for graded manifolds

Hsuan-Yi Liao, Mathieu Stiénon

We introduce, for every -graded manifold, a formal exponential map defined in a purely algebraic way and study its properties. As an application, we give a simple new c…
