View source for Absolute Cesàro summability

A sequence or series is said to be absolutely summable by a given [[Matrix summation method|matrix summation method]] if the sequence or series obtained by the transformation involved is absolutely convergent. See [[Absolute summability|Absolute summability]].

Thus, one has absolute Cesàro summability, absolute Euler summability, absolute Nörlund summability, absolute Riesz summability, absolute Voronoi summability (which is the same as absolute Nörlund summability), and, more generally, absolute matrix summability.
