We introduce, for every Z\mathbb{Z}-graded manifold, a formal exponential map defined in a purely algebraic way and study its properties.

This paper aims at setting out the basics of Z\mathbb{Z}-graded manifolds theory. We introduce Z\mathbb{Z}-graded manifolds from local models and give some of their properties. The requirement to work with a completed graded symmetric algebra to define functions is made clear. Moreover, we define vector fields and ex…

The pull back of a flat bundle EXE\rightarrow X along the evaluation map π:LXXπ: \mathcal{L} X \to X from the free loop space LX\mathcal{L} X to XX comes equipped with a canonical automorphism given by the holonomies of EE. This construction naturally generalizes to flat Z\mathbb{Z}-graded connections on XX. Our main …

The aim of this article is to introduce and study certain topological invariants for closed, oriented three-manifolds Y. These groups are relatively Z-graded Abelian groups associated to SpinC structures over Y. Given a genus g Heegaard splitting of Y, these theories are variants of the Lagrangian Floer homology for th…

Heegaard Floer homology, first introduced by P. Ozsvath and Z. Szabo, associates to a 3-manifold Y a family of relatively graded Abelian groups HF(Y,t), indexed by Spin^c structures t on Y. In the case that Y is a rational homology sphere, Ozsvath and Szabo lift the relative Z-grading to an absolute Q-grading. This ind…

In [1] it was shown that K^, a certain differential cohomology functor associated to complex K-theory, satisfies the Mayer-Vietoris property when the underlying manifold is compact.

We discuss generalizations of Ozsvath-Szabo's spectral sequence relating Khovanov homology and Heegaard Floer homology, focusing attention on an explicit relationship between natural Z (resp., 1/2 Z) gradings appearing in the two theories.

We define \textit{graded manifolds} as a version of supermanifolds endowed with an additional Z\mathbb Z-grading in the structure sheaf, called \textit{weight} (not linked with parity). Examples are ordinary supermanifolds, vector bundles over supermanifolds, double vector bundles, iterated constructions like TTMTTM, e…

We give an exposition of graded and microformal geometry, and the language of QQ-manifolds. QQ-manifolds are supermanifolds endowed with an odd vector field of square zero. They can be seen as a non-linear analogue of Lie algebras (in parallel with even and odd Poisson manifolds), a basis of "non-linear homological a…

We develop a method of calculation for the symplectic Floer homology of composite knots. The symplectic Floer homology of knots defined in \cite{li} naturally admits an integer graded lifting, and it formulates a filtration and induced spectral sequence. Such a spectral sequence converges to the symplectic homology of …
