Research on Optimal Quadrature Problems in the W2(9,0) Space

Year: 2026

Type: article

Abstract: In this paper, we derive an explicit expression for the coefficients of optimal quadrature formulas that are exact for exponential trigonometric functions in the W2(9,0) space. The optimal quadrature formulas are constructed based on Sard’s sense for Sobolev’s method.
