主要著書
1. Lin WENG, Zeta Functions for Reductive Groups and Their Zeros, World Scientific, pp 528+xxvii, 2018.02, [URL], In this book, we develop a basic theory for new yet genuine zeta functions functions for number fields, establish the spacial uniformity of zeta functions on the equivalence of rank n non-abelian zeta functions and SL(n)-zeta functions, based on Siegel-Langland' theory of Eisenstein series. In particular, we confirm a central conjecture on "Parabolic Reduction, Stability and the Volumes". The key to this is an analytic version of the Mumford'S GIT correspondence between un-stable principle bundles and the parabolic subgroups of the associated reductive groups. This itself is based on an equivalence between Arthur's analytic truncation on the adelic spaces and the geo-arithmetic truncation of stability on principal bundles. Finally, we prove the Riemann hypothesis for our zeta functions. The book consists of 7 parts: Part 1 Non-Abelian Zeta Function Part 2 Rank 2 Zeta Functions Part 3 Eisensetin Periods and Multiple Zeta Functions Part 4 Zeta Functions for Reductive Groups Part 5 Algebraic and Analytic Structures and Riemann Hypothesis Part 6 Geometric Structures and Riemann Hypothesis Appendices (with K. Sugahara) Five Essays On Arithmetic Cohomology.

1. Lin WENG, Don Zagier, Higher-rank zeta functions and $SL_n$-zeta functions for curves, 米国科学アカデミー紀要(PNAS), PNAS March 24, 2020 117 (12), PNAS March 24, 2020 117 (12), 6398-6408, 2020.03, [URL], In earlier papers L.Weng introduced two sequences of higher-rank zeta functions associated to a smooth projective curve over a finitefield, both of them generalizing the Artin zeta function of the curve. One of these zeta functions is defined geometrically in terms ofsemistable vector bundles of rank n over the curve, and the other one group-theoretically in terms of certain periods associated to thecurve and to a split reductive group G and its maximal parabolic subgroup P. It was conjectured that these two zeta functions coincidein the special case when G = $SL_n$ and $P$ is the parabolic subgroup consisting of matrices whose final row vanishes except for its lastentry. In this paper we prove this equality by giving an explicit inductive calculation of the group-theoretically defined zeta functions interms of the original Artin zeta function (corresponding to n = 1) and then verifying that the result obtained agrees with the inductivedetermination of the geometrically defined zeta functions found by Sergey Mozgovoy and Markus Reineke in 2014..

Zagier, Higher rank zeta functions for elliptic curves, 米国科学アカデミー紀要(PNAS), PNAS March 3, 2020 117 (9), PNAS March 3, 2020 117 (9), 4546-4558, 2020.02, [URL], The rank n non-abelian zeta functions for curves over finite fields was defined by the first author in 2005, using moduli stacks of rank n semi-stable vector bundles on curves. These zeta functions satisfy the standard zeta properties such as the rationality, the functional equation and are conjectured to satisfy the Riemann Hypothesis. In particular, when n=1, these zeta functions coincide with the famous Artin zeta functions.In this paper, we prove the Riemann hypothesis for non-abelian zeta functions of elliptic curves..
