A new trigonometric method of summation and its application to the degree of approximation
The authors introduce a new trigonometric method of summation being both regular and Fourier effective. They also define a new Banach space where the definition of the norm is given by a further generalization of the generalized Hölder metric. An application of their new method of summation is applied to determine the degree of approximation in the new space.
