โœฆ Synopsis


Let R be an n-dimensional affine domain over a field k, where k is either perfect or char k s 0. Let J be the Jacobian ideal of R. In this paper, we prove s n q1 ลฝ . that there exists an integer s such that J Ext M, N s 0 for all finitely R generated R-modules M and N.

## Abstract The category of Scottโ€domains gives a computability theory for possibly uncountable topological spaces, via representations. In particular, every separable Banachโ€space is representable over a separable domain. A large class of topological spaces, including all Banachโ€spaces, is represe
