Chow groups of symmetric products of projective space

Youming Chen, Wenchuan Hu

We prove that the integral cycle class map for $\SP^d(\PP^n)$ is split injective, with finite cokernel annihilated by $d!$ ,and we determine the ranks of Chow groups for $\mathrm{SP…

Lawson homology groups of Chow varieties

Youming Chen, Wenchuan Hu

Let $C_{p, d} (P^{n})$ denote the Chow variety of effective algebraic $p$ -cycles of degree $d$ in complex projective space $P^{n}$ . In this paper, we compute the ration…

The equivalence of Friedlander-Mazur and standard conjectures for threefolds

Jin Cao, Wenchuan Hu

We show that the Friedlander-Mazur conjecture holds for a complex smooth projective variety X of dimension three implies the standard conjectures hold for X. This together with a r…

The multiplicative group action on singular varieties and Chow varieties

Wenchuan Hu

We answer two questions of Carrell on a singular complex projective variety admitting the multiplicative group action, one positively and the other negatively. The results are appl…

Holomorphic vector fields and Chow groups

Wenchuan Hu

We show that the chow group of $p$ -cycles with rational coefficients are isomorphic to the corresponding rational homology groups for smooth complex projective varieties carrying a…
