Abstract. In this paper, denotes a complete, non-trivially valued, non-archimedean field. The entries of sequences, series and infinite matrices are in
. In the present paper, we prove the Knopp's core theorem for double sequences in
and also the necessary and sufficient conditions for the core to be invariant under the four dimensional matrix transformation in such fields.
