Algebraic and Arithmetic Structures of Moduli Spaces edited by I. Nakamura & L. Weng Advanced Studies in Pure Mathematics, 58 Math Soc. Japan, 2010 
The conference "Algebraic and Arithmetic Structures of Moduli Spaces" was held in September 2007, at Sapporo (Hokkaido university). Twenty talks were delivered by invited speakers on arithmetic geometry, algebraic geometry and complex geometry. This volume is the proceedings of the conference, to be exact, a collection of eleven papers contributed by some of the speakers which have undergone rigorous refereeing. The topics that are discussed in the articles are diverse in nature such as class field theory, zeta functions, moduli of arithmetic vector bundles, moduli of complex vector bundles, moduli of abelian varieties and theory of display, moduli of Fermat varieties and some topics on cubic threefolds. Among others, the papers of PappasRapoport, Rajan and Weng address many new interesting questions in the related fields, which seem to be worthy of reading for young researchers.  
Conference on $\small{L}$Functions edited by L. Weng & M. Kaneko World Scientific 
This invaluable volume collects papers written by many of the world's top experts on Lfunctions. It not only covers a wide range of topics from algebraic and analytic number theories, automorphic forms, to geometry and mathematical physics, but also treats the theory as a whole. The contributions reflect the latest, most advanced and most important aspects of Lfunctions. In particular, it contains Hida's lecture notes at the conference and at the Eigenvariety semester in Harvard University and Weng's detailed account of his works on high rank zeta functions and nonabelian Lfunctions.  
Arithmetic Geometry and Number Theory edited by L. Weng & I. Nakamura World Scientific, 2006 
Mathematics is very much a part of our culture; and this invaluable collection serves the purpose of developing the branches involved, popularizing the existing theories and guiding our future explorations. More precisely, the goal is to bring the reader to the frontier of current developments in arithmetic geometry and number theory through the works of DeningerWerner in vector bundles on curves over padic fields; of Jiang on local gamma factors in automorphic representations; of Weng on Deligne pairings and TakhtajanZograf metrics; of Yoshida on CMperiods; of Yu on transcendence of special values of zetas over finite fields. In addition, the lecture notes presented by Weng at the University of Toronto from October to November 2005 explain basic ideas and the reasons (not just the language and conclusions) behind Langlands' fundamental, yet notably difficult, works on the Eisenstein series and spectral decompositions. And finally, a brand new concept by Weng called the Geometric Arithmetic program that uses algebraic and/or analytic methods, based on geometric considerations, to develop the promising and yet to be cultivated land of global arithmetic that includes nonabelian Class Field Theory, Riemann Hypothesis and nonabelian Zeta and L Functions, etc.
