摘要翻译:
我们首先回顾了适当曲面的Chow运动模型交上同调的构造,并研究了它的基本性质。利用Voevodsky的有效几何动因范畴,我们研究了非奇异爆破中例外因子的动因。如果除数的所有几何不可约分量都是零亏格,那么Voevodsky的形式允许我们构造Chow动机的某些单扩张,作为具有曲面光滑部分紧支撑的动机的正则子商。专门针对Hilbert-Blumenthal曲面,我们恢复了a.Caspar最近构造的母题解释。

英文摘要:
We first recall the construction of the Chow motive modelling intersection cohomology of a proper surface and study its fundamental properties. Using Voevodsky's category of effective geometrical motives, we then study the motive of the exceptional divisor in a non-singular blow-up. If all geometric irreducible components of the divisor are of genus zero, then Voevodsky's formalism allows us to construct certain one-extensions of Chow motives, as canonical sub-quotients of the motive with compact support of the smooth part of the surface. Specializing to Hilbert--Blumenthal surfaces, we recover a motivic interpretation of a recent construction of A. Caspar.
