{wiki=Pólya–Szegő_inequality}

The Pólya–Szegő inequality is a result in the field of mathematics, particularly in the area of functional analysis and inequalities. It provides a comparison of certain integral expressions that involve non-negative functions, and it is often used in the context of orthogonal polynomials and convex functions. More specifically, the Pólya–Szegő inequality deals with the integrals of non-negative functions defined on the interval \\(\[0, 1\]\\).
