ON THE REGION FOR CONVERGENCE OF TRIGONOMETRIC INTERPOLATION FOR ANALYTIC FUNCTIONS
Supported by NNSF and RFDP of Higher Education of China, and fund of Wuhan University.
In this paper, the convergence of the trigonometric interpolation for 2π-periodic analytic functions on [0,2π] with a sequence of preassigned nodal sets are discussed.
- Trigonometric interpolation
- Perfect convergence
- Full convergence
- Convergence with preassigned nodal sets
