我们使用分段多项式来定义热带cocycles推广的热带卡地亚因子更高的余维著名的概念。上循环群是Chow上同调群的热带类似群。我们还介绍了交叉产品的上循环与热带循环-对应的经典帽产品-并证明,这引起了庞加莱对偶在某些情况下。
We use piecewise polynomials to define tropical cocycles generalising the well-known notion of tropical Cartier divisors to higher codimensions. Groups of cocycles are tropical analogues of Chow cohomology groups. We also introduce an intersection product of cocycles with tropical cycles - the counterpart of the classical cap product - and prove that this gives rise to a Poincar\'e duality in some cases.
