Let (u n ) be a sequence of real numbers. We obtain some Tauberian-like conditions in terms of the general control modulo of integer order to retrieve subsequential convergence of (u n ) from the boundedness of (u n ).

✦ Synopsis
In this work we prove that one-sided slow oscillation of a sequence and that of its generator sequence are Tauberian conditions for the Abel summability method, using a corollary to Karamata's Main Theorem [J. Karamata, Über die Hardy-Littlewoodschen Umkehrungen des Abelschen Stetigkeitssatzes, Math. Z. 32 (1930) 319-320]. It is also shown that such conditions are Tauberian conditions for generalized Abelian summability methods.
