正则化精炼对称多重 zeta 值的 Ohno 关系

Ohno relation for regularized refined symmetric multiple zeta values

本文将 Ohno 关系从精炼对称多重 zeta 值进一步推广到正则化精炼对称多重 zeta 值，即从 $0$ 到 $0$ 的非容许迭代积分情形。

On the Non-vanishing of the Central Value of Certain L-functions: Unitary Groups

Let $π$ be an irreducible cuspidal automorphic representation of a quasi-split unitary group ${\rm U}_{\mathfrak n}$ defined over a number field $F$. Under the assumption that $π$ has a generic global Arthur parameter, we establish the non-vanishing of the central value of $L$-functions, $L(\frac{1}{2},π\timesχ)$, with a certain automorphic character $χ$ of ${\rm U}_1$, for the case of ${\mathfrak n}=2,3,4$, and for the general ${\mathfrak n}\geq 5$ by assuming a conjecture on certain refined properties of global Arthur packets. In consequence, we obtain some simultaneous non-vanishing results…
