- Abstract
The article focuses on the use of Jackson-Stechkin type inequalities for the study of periodic functions. It says that computing Jackson-Stechkin sharp constants is an external problem of function approximation theory. It also mentions several mathematical methods related to periodic functions including Minkowski's inequality, Rolle's theorem, and Fourier coefficients.
