In algebra, a locally compact field is a topological field whose topology forms a locally compact Hausdorff space.[1] These kinds of fields were originally introduced in p-adic analysis since the fields are locally compact topological spaces constructed from the norm on . The topology (and metric space structure) is essential because it allows one to construct analogues of algebraic number fields in the p-adic context.
