Higher-dimensional logarithmic derivatives
Sarah Zerbes (Imperial College, London)


     In my talk, I will explain how to construct logarithmic derivative maps for n-dimensional local fields of mixed characteristic (0,p). The main ingredients for this construction are higher-dimensional rings of overconvergent series and Tony Scholl's work on general fields of norms. As an application of the logarithmic derivative, I will give a new construction of Kato's dual exponential map for K_n.
