Extensions of self-dual orders
Published online by Cambridge University Press: 24 October 2008
Extract
We give a new criterion for an order in a commutative split algebra over the quotient field of a discrete valuation ring R to be self-dual. We derive a result on the ideal classes whose order is an extension by R of a self-dual order. This yields a wide generalization of a theorem of Faddeev(1). We can also answer a question arising from a paper of Fröhlich(2).
