Abstract
The four-dimensional summability methods of Euler and Borel are studied as mappings from absolutely convergent double sequences into themselves. Also the following Tauberian results are proved: if x = (xm,n) is a double sequence that is mapped into ℓ2 by the four-dimensional Borel method and the double sequence x satisfies (Formula presented.) and (Formula presented.), then x itself is in ℓ2.
