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.
