摘要:Let R be a discrete valuation ring with fraction field K. In this talk, we consider degenerations of a class of abelian varieties over K, namely the ones which admit good reduction over a tamely ramified finite field extension of K. They extend uniquely to “ket log abelian schemes” over R which is regarded as a log scheme with respect to the log structure associated to a chosen uniformizer of R. We will first give a brief introduction to log schemes and Kummer log etale (ket) topology. Then we define ket abelian schemes to be ket sheaves which are (ket) locally just abelian schemes. At last we state and show our degeneration result.
