A Hilbertian approach to quasi interpolation methods

Neural Parallel Sci. Comput., 1997
An abstract approach to quasi-interpolation methods based on the Hilbertian theory of integral kernels is developed. The error estimates in the energy norm are obtained for the relevant quasi-interpolants. A new approximating operator adapted to the data function, satisfying given boundary conditions, is introduced.

The method of left Baskakov quasi-interpolants.

2002
Summary: The optimal degree of approximation of the method of Baskakov operators \(V_n\) on the space \(C_b[0,\infty)\) is known to be \(O(n^{-1})\). In order to obtain much faster convergence, a family of intermediate operators between \(V_n\) and the identity operator, the so-called left Baskakov quasi-interpolants \(V_n^{(k)}\) in the sense of ...
