Rational Approximation and Sobolev-type Orthogonality

Abel Díaz-González, Héctor Pijeira-Cabrera, Ignacio Pérez-Yzquierdo

In this paper, we study the sequence of orthogonal polynomials $\{S_n{\}}_{n=0}^{\infty }$ with respect to the Sobolev-type inner product $$\langle f,g \rangle= \int_{-1}^{1} f(x) g(x…
