On the Absolute Cesaro Summability of Negative Order of a Series Associated with the Conjugate Series of a Fourier Series
1. Definition. Let λ ≡ λ( ω ) be continuous, differentiable, and monotonie increasing in (0, ∞) and let it tend to infinity as ω → ∞. A series a n is summable | R , λ, r |, where r > 0, if where A is a fixed positive …
