Abstract

We give explicit formulas for the local topological zeta functions at the origin of generic symmetric determinantal varieties and catalecticant determinantal varieties associated with generic Hankel matrices. In the symmetric determinant hypersurface case, the formula simplifies to a closed product expression and implies the Strong Monodromy Conjecture. For catalecticant determinantal varieties, we establish a simultaneous local reduction of the determinantal ideals and obtain a closed product formula for their local topological zeta functions. Together with the known Bernstein-Sato polynomial of the Hankel determinant, this also implies the Strong Monodromy Conjecture in the square catalecticant determinant case. The method used in this paper also gives short proofs of Chen-Zuo/Docamposs formula in the generic determinantal case and Chen-Shi-Xu-Zuo's formula in the skew-symmetric case.

Ceresa Cycles of $X_{0}(N)$

The Ceresa cycle is an algebraic 1-cycle on the Jacobian of an algebraic curve. Although it is homologically trivial, Ceresa famously proved that for a very general complex curve of genus at least 3, it is non-trivial in the Chow group. In this paper we study the Ceresa cycle attached to the complete modular curve $X_{0}(N)$ modulo rational equivalence. For prime level $p$ we give a complete description, namely we prove that if $X_{0}(p)$ is not hyperelliptic, then its Ceresa cycle is non-torsion. For general level $N$, we prove that there are finitely many $X_{0}(N)$ with torsion Ceresa cycle. Our method relies on the relationship between the vanishing of the Ceresa cycle and Chow-Heegner points on the Jacobian. We use the geometry and arithmetic of modular Jacobians to prove that such points are of infinite order and therefore deduce non-vanishing of the Ceresa cycle.

Uniform vector bundles over $\mathbb{P}^4$

There is a long-standing conjecture which states that every uniform algebraic vector bundle of rank $r<2n$ on the $n$-dimensional projective space $\mathbb{P}^n$ over an algebraically closed field of characteristic $0$ is homogeneous. This conjecture is valid for $n\leq3$. In this paper, we classify all uniform vector bundles of rank $r<8$ over $\mathbb{P}^4$ and show that the conjecture holds for $n=4$.

Splitting vector bundles over real algebraic varieties

Suppose $X$ is a smooth affine real variety and $\mathscr{E}$ is a vector bundle over $X$. We analyze the problem of splitting off a free rank one summand from $\mathscr{E}$ in corank $0$ and $1$. The problem in corank $0$ can be viewed as the search for a real analog of Murthy's celebrating splitting theorem in the algebraically closed case: to wit, beyond the vanishing of the top Chern class in Chow theory, are the obstructions to splitting ``purely topological''? In a sense, the answer in this case is yes, and we give a proof, using motivic techniques, of a mild extension of the results of Bhatwadekar-Sridharan and Bhatwadekar-Das-Mandal. In corank $1$, in the algebraically closed situation, Murthy's splitting conjecture (now a theorem in characteristic $0$) predicts that the vanishing of the top Chern class in Chow theory is the only obstruction to splitting off a free rank $1$ summand, and we can search for a suitable ``real'' analog of this assertion. We observe that several natural guesses for a ``real'' analog of Murthy's splitting conjecture cannot be true, i.e., that the situation over the real numbers is rather complicated.
