Aims & Scope✦ Inferred from recent articles

The journal publishes research on approximation theory, including topics such as randomized algorithms for approximation, multiple orthogonal polynomials and their factorizations, and moment problems related to Jacobi operators. It also covers inequalities like Landau-type inequalities and anisotropic polynomial approximation in Lebesgue and Besov spaces. Further research includes the use of polynomial frames for detecting discontinuities along curves on spheres.
