论文摘要
我们研究Chern Coners的动机。首先，我们展示了光滑曲线的投影锥的示例，以使它们的各种$ k $类别（伪造理论，推动和动机）都不同。然后，我们展示了托型式旋转品种及其仿射锥体的圆环的动机阶级之间的联系，从而将结果推广到投影性的thom多项式。
We study motivic Chern classes of cones. First we show examples of projective cones of smooth curves such that their various $K$-classes (sheaf theoretic, push-forward and motivic) are all different. Then we show connections between the torus equivariant motivic Chern class of a projective variety and of its affine cone, generalizing results on projective Thom polynomials.
