Denis Osipov Steklov Mathematical Institute, Russia Gerbes and symbolsWe consider construction of the 2-dimensional tame symbol on a 2-dimensional local field as monodromy of some combinatorial gerbe. From this construction we prove up to sign the Parshin reciprocity laws for these symbols for any algebraic surfaces over any perfect ground field. Go to the Laboratoire Poncelet home page. |
