摘要翻译:
我们定义并研究了完美域上混合动机上的Gysin态射。我们的构造将从Voevodsky的结果中已知的闭浸入的情形推广到任意射影态射。在此背景下,我们证明了几个经典公式,如投影和超额交公式,以及一些涉及残差的原始公式。最后,我们给出了这个结构在紧支撑对偶和动机上的应用。

英文摘要:
We define and study Gysin morphisms on mixed motives over a perfect field. Our construction extends the case of closed immersions, already known from results of Voevodsky, to arbitrary projective morphisms. We prove several classical formulas in this context, such as the projection and excess intersection formulas, and some more original ones involving residues. Finally, we give an application of this construction to duality and motive with compact support.
