# On the ring structure of spark characters

@article{Hao2008OnTR, title={On the ring structure of spark characters}, author={Ning Hao}, journal={arXiv: Differential Geometry}, year={2008} }

We give a new description of the ring structure on the differential characters of a smooth manifold via the smooth hyperspark complex. We show the explicit product formula, and as an application, calculate the product for differential characters of the unit circle. Applying the presentation of spark classes by smooth hypersparks, we give an explicit construction of the isomorphism between groups of spark classes and the $(p,p)$ part of smooth Deligne cohomology groups associated to a smooth…
