A Mathematical Gift, II

Autor: Kenji Ueno, Koji Shiga, Shigeyuki Morita

This is the second of three volumes originated from a series of lectures in mathematics given by professors of Kyoto University in Japan for high school students (the translation of the first volume was published by the AMS in 2003). The main purpose

In this paper, the development of an accelerating structure with high-purity copper operated at approximately 20 K is described. The aim is to obtain a dramatic increase in the quality factor (Q factor), which is an important parameter as regards enh

We introduce a formal group naturally associated with algebraic curves. The formal group is isomorphic to the one obtained from the universal Witt scheme. The charge zero sector of the boson Fock space is regarded as the coordinate ring of the formal

Advances in Moduli Theory

Autor: Yuji Shimizu, Kenji Ueno

This book aims to study several aspects of moduli theory from a complex analytic point of view. Chapter 1 gives a brief introduction to the Kodaira-Spencer deformation theory of compact complex manifolds. In Chapter 2 we discuss the analytic theory o
