Inclusion results for convolution submethods
Summary: If \(B\) is a summability matrix, then the submethod \(B_\lambda\) is the matrix obtained by deleting a set of rows from the matrix \(B\). Comparisons between Euler-Knopp submethods and the Borel summability method are made. Also, an equivalence result for convolution submethods is established. This result will necessarily apply to the submethods of the Euler-Knopp, Taylor, Meyer-König, and Borel matrix summability methods.
